Kacy Byxbee: Inside Scott Caan’s Longtime Partner’s Costume Career, Hawaii Five-0 Connection, Daughter and Private Family Life

Kacy Byxbee is an American costume and wardrobe professional best known publicly as the longtime partner of Scott Caan, the actor who played Danny “Danno” Williams on Hawaii Five-0. But Kacy has her own connection to television: she worked in the costume department of Hawaii Five-0, where she and Scott reportedly met. The couple later welcomed their daughter, Josie James Caan, in July 2014.

Kacy is unusually private for someone connected to a famous Hollywood family. She does not give frequent interviews, and dependable information about her childhood, exact age, education and current projects is limited. What can be verified paints a simpler picture: she worked behind the camera, formed a long-term relationship with Scott and became part of the Caan family without trying to turn that connection into a celebrity career.

Quick Bio of Kacy Byxbee

IMDb credits Kacy with costume and wardrobe work on Somewhere, Hawaii Five-0 and All at Once. Its records list her on 69 episodes of Hawaii Five-0 between 2011 and 2014.

Who Is Kacy Byxbee?

Kacy Byxbee became familiar to entertainment fans because of Scott Caan, but she was not simply someone accompanying an actor to premieres.

She worked behind the scenes.

Costume departments are an essential part of filmmaking and television production. They help prepare, organize and maintain the clothing performers wear while filming.

Kacy’s credits show that she worked professionally in this area.

IMDb lists her under the costume and wardrobe department rather than as an actress or model.

That distinction matters because some online profiles incorrectly describe her as a model simply because photographs show her attending red-carpet events.

Her documented professional work is in wardrobe.

Kacy Byxbee Worked on Hawaii Five-0

Kacy’s most substantial publicly documented credit is CBS’s Hawaii Five-0.

IMDb lists her as a costumer on the series from 2011 through 2014, covering 69 episodes. Individual episode records from 2011, 2012 and 2013 also identify her in the costume and wardrobe department.

That is not a tiny one-day credit.

Working across dozens of episodes means becoming part of the production machinery that keeps a television series running.

A network drama can have multiple characters, guest stars, stunt doubles and continuity requirements.

Wardrobe professionals help ensure everything remains organized from scene to scene.

Kacy’s work therefore happened away from the camera but was part of the same production viewers watched each week.

What Does a Costumer Actually Do?

A costumer’s work is practical as well as creative.

Actors may need several versions of the same outfit.

Clothes can become damaged during action scenes.

A story may jump backward or forward in time.

Characters may change clothes several times in one episode.

The wardrobe team needs to know exactly what belongs in each scene.

That means attention to detail is essential.

Kacy’s repeated Hawaii Five-0 credits indicate that she worked within this demanding production environment for several seasons.

It also explains how her professional life eventually crossed with Scott’s.

How Did Kacy Byxbee Meet Scott Caan?

Kacy and Scott reportedly met through Hawaii Five-0.

Scott was one of the show’s main actors, playing Detective Danny Williams.

Kacy worked in the costume department.

E! reported in 2014 that the couple had been dating for at least several years after meeting on the show’s set.

That makes their relationship another example of two people meeting through a television production while working in completely different departments.

Scott’s job happened in front of the camera.

Kacy’s happened behind it.

The set brought them together.

Scott Caan Played Danny Williams for a Decade

Scott joined Hawaii Five-0 when the reboot premiered in 2010.

He played Danny “Danno” Williams alongside Alex O’Loughlin’s Steve McGarrett.

The role became one of Scott’s best-known performances and earned him a Golden Globe nomination. He remained with the series through its conclusion in 2020.

That made Hawaii a major part of Scott’s life.

It also became important to his relationship with Kacy.

In a 2013 television interview, Scott talked about living with his girlfriend while working in Hawaii. E!’s later coverage identified that girlfriend as Kacy.

The couple were already well established before becoming parents.

Scott Publicly Joked About Life With Kacy

Scott is generally private, but he has occasionally spoken about his relationship.

During a 2013 appearance on Chelsea Lately, he jokingly said his girlfriend deserved a Purple Heart because he was “a complete disaster.”

E! later quoted the comment while reporting on the birth of their daughter and identified Kacy as his live-in partner.

The joke gives a small glimpse into their relationship without revealing too much.

That has remained the pattern.

Scott might mention family in an interview, but neither he nor Kacy has built a public brand around their relationship.

For a couple connected with Hollywood for more than a decade, they have kept surprisingly much to themselves.

Kacy and Scott Appeared at the Emmy Awards

One of Kacy’s notable public appearances came in September 2011.

She accompanied Scott to the 63rd Primetime Emmy Awards in Los Angeles.

Photographs from the ceremony show the couple together on the red carpet.

At that point, Hawaii Five-0 was still relatively new, and Scott’s role as Danny Williams was increasing his television visibility.

Kacy’s appearance also provides evidence that their relationship stretches back well over a decade.

It was not a recent romance created by social-media speculation.

They were appearing publicly together years before becoming parents.

Kacy Byxbee and Scott Caan Became Parents in 2014

In 2014, news emerged that Kacy was pregnant with the couple’s first child.

The pregnancy was not turned into a large publicity campaign.

E! reported that the couple welcomed a daughter named Josie James Caan on July 9, 2014.

IMDb’s record for Kacy confirms the same date and identifies Josie as her first child with Scott.

Scott was 37 at the time.

For Kacy and Scott, parenthood created another reason to keep their personal world separate from Hollywood publicity.

Who Is Josie James Caan?

Josie James Caan is Kacy and Scott’s daughter.

She was born July 9, 2014, making her 12 years old as of September 2026.

Because Josie is still a child, detailed personal information about her should remain private.

She is not a professional celebrity simply because her father and grandfather are famous.

What is publicly known is that Scott has spoken warmly about becoming a parent and that his father, James Caan, was delighted by his granddaughter.

Josie’s middle name also carries an obvious family connection.

It is James.

Josie’s Famous Grandfather Was James Caan

Kacy’s daughter belongs to a major Hollywood family.

Her paternal grandfather was James Caan, one of the best-known actors of his generation.

James became famous for playing Sonny Corleone in The Godfather and built a career that included Misery, Thief, Brian’s Song, Elf and many other films.

Scott was James Caan’s son with actress and model Sheila Ryan.

People’s recent profile of James’ children notes that Scott later honored his father through his daughter Josie’s middle name.

James died in July 2022 at age 82.

That made Josie’s middle name an even more meaningful family connection.

James Caan Adored His Granddaughter

James Caan spoke affectionately about his grandchildren.

Accounts of the family have highlighted how proud he was of Josie.

That relationship added another dimension to Kacy’s connection with the Caan family.

She was not simply Scott’s partner attending premieres.

She and Scott had created the next generation of the family.

People’s 2026 profile of James Caan’s five children identifies Scott as a father and notes the special family meaning behind Josie James Caan’s name.

For a Hollywood family stretching across generations, Josie became an important link between Scott and his father.

Is Kacy Byxbee Scott Caan’s Wife?

This question is more complicated than many online biographies suggest.

For years, reliable reporting consistently described Kacy as Scott’s girlfriend or partner.

E!’s 2014 birth report called her his girlfriend. IMDb’s biography likewise describes her relationship with Scott and their daughter.

More recently, some biographical databases—including Scott’s current Wikipedia entry—label Kacy as his spouse.

However, widely reported details of a wedding—such as a confirmed marriage date and ceremony—are difficult to find in stronger mainstream coverage.

For that reason, the most cautious description remains Scott Caan’s longtime partner unless a clearly documented marriage record or direct announcement establishes more.

They have unquestionably shared a long-term family relationship.

The precise legal label is less clearly documented.

How Long Have Kacy and Scott Been Together?

Their relationship has lasted well over a decade.

They were already appearing together publicly in 2011.

Scott discussed living with his girlfriend in 2013.

They became parents in 2014.

Public event photographs continued showing them together after Josie’s birth, including the 2015 premiere of Entourage and the New York premiere of Rock the Kasbah later that year.

That creates a relationship timeline stretching back to at least the early 2010s.

For a Hollywood couple, it is notably long.

Even more unusual is how little they have said publicly about it.

Kacy Attended the Entourage Premiere With Scott

In June 2015, Kacy joined Scott at the Los Angeles premiere of Entourage.

Scott had appeared in the original HBO television series as talent manager Scott Lavin.

The premiere therefore connected directly with another important part of his acting career.

Kacy appeared alongside him wearing a white lace outfit while Scott wore a light gray suit.

By then, they were already parents to Josie.

The appearance shows that becoming parents did not completely remove them from public events.

But such appearances remained occasional rather than constant.

Kacy never became a professional red-carpet personality.

They Also Attended the Rock the Kasbah Premiere

Later in 2015, Kacy and Scott appeared together at the New York premiere of Rock the Kasbah.

Once again, photographs captured them posing together.

These images are useful because Kacy herself rarely speaks publicly.

Much of her documented public timeline comes from professional credits and occasional appearances alongside Scott.

Even during periods when photographers regularly captured the couple, they rarely gave detailed interviews about their relationship.

Their public presence was visible.

Their private life remained protected.

That balance has continued for years.

Kacy Byxbee’s Other Film Credits

Hawaii Five-0 is Kacy’s largest documented television credit, but it is not her only wardrobe work.

IMDb also credits her on Sofia Coppola’s 2010 film Somewhere.

The film starred Stephen Dorff and Elle Fanning and won the Golden Lion at the Venice Film Festival.

Kacy later worked on the 2016 film All at Once, where IMDb lists her in wardrobe.

These credits help establish that wardrobe was a genuine professional career rather than simply a role she held because Scott happened to star on Hawaii Five-0.

Her work existed beyond their relationship.

Is Kacy Byxbee a Costume Designer?

She is frequently called a “costume designer” online, but her documented credits are more specific.

IMDb generally places Kacy in the costume and wardrobe department and credits her as a costumer on Hawaii Five-0.

That is not exactly the same as being the overall costume designer.

A costume designer normally leads the visual concept for a production’s clothing.

Costumers and wardrobe staff help execute and maintain those designs during production.

Both roles are important, but they should not be confused.

So “costume and wardrobe professional” or “costumer” is the most precise description supported by her credits.

Did Kacy Byxbee Work on 69 Episodes of Hawaii Five-0?

Yes.

IMDb currently credits Kacy with work on 69 episodes of Hawaii Five-0 between 2011 and 2014.

Individual episode credits reinforce this.

For example, she is listed as a costumer on episodes from 2011, 2012 and 2013.

That gives us a clearer picture of her career than vague claims about her being a “fashion expert.”

She worked on a demanding network television production for several years.

And it was through that work that her personal and professional stories became connected.

Why Did Kacy Leave Hawaii Five-0?

IMDb’s listed run ends in 2014.

That happens to be the same year she gave birth to Josie.

It may be tempting to say she left the show specifically to become a full-time mother.

However, there is no reliable public statement from Kacy confirming that explanation.

Timelines can overlap without proving cause.

She may have changed projects for many possible reasons.

What can safely be said is that her documented Hawaii Five-0 wardrobe work ran through 2014, and she became a mother that July.

Anything beyond that should be identified as speculation.

What Is Kacy Byxbee Doing Today?

Kacy’s current professional activity is not extensively documented.

Her IMDb page lists All at Once in 2016 among her later wardrobe credits, but it does not show a long series of recent high-profile film and television jobs.

That does not mean she stopped working altogether.

Crew professionals can work under different circumstances, move between industries or simply have projects that attract little celebrity coverage.

Kacy herself has not made her career into a public story.

As of 2026, she remains best documented through her earlier wardrobe work and long-term family relationship with Scott.

Kacy Has Never Chased Celebrity Fame

This may be the most consistent feature of Kacy’s public life.

She had a direct professional connection to television.

Her partner became famous through film and TV.

Her father-in-law was a Hollywood legend.

Yet Kacy never seemed interested in becoming famous simply because famous people surrounded her.

She did not build a reality show around the Caan family.

She did not become a regular celebrity interviewer.

She did not turn motherhood into influencer content.

Instead, she remained primarily known through her behind-the-scenes career and occasional public appearances.

That is unusual enough to become part of her story.

Scott Caan Is More Than an Actor

Kacy’s partner also has creative interests outside acting.

Scott is a photographer, writer and former rapper in addition to his screen career. His biography records his early hip-hop work as part of The Whooliganz with The Alchemist, where he performed under the name Mad Skillz.

He later moved into acting and became known for films such as Varsity Blues and the Ocean’s Eleven trilogy.

Photography became another serious creative interest.

That may help explain why Scott and Kacy have managed a relatively private family life.

Both understand entertainment production without appearing to need constant celebrity attention.

Their careers have involved creative work, not simply publicity.

Kacy and Scott’s Hawaii Years

For several years, Hawaii was central to the couple’s lives.

Scott was filming Hawaii Five-0.

Kacy worked in wardrobe on the same production.

Their relationship developed there.

Scott even discussed the unusual pace of Hawaiian life during his 2013 interview, joking that the island environment felt much slower than the energy he preferred. E!’s coverage noted that he and Kacy were living together during this period.

Those Hawaii years therefore combined work, romance and eventually preparations for parenthood.

For Kacy, the show was more than another résumé credit.

It became connected with a major chapter of her personal life.

Scott Caan’s Relationship With His Father

James Caan was not always an easy father, and Scott has spoken about their complicated family history.

But father and son became close.

People’s recent profile notes that James even stepped away from parts of his career at one stage to coach Scott’s Little League team. Later, Scott and James worked together on the film Mercy.

When Scott became a father himself in 2014, another generation entered that relationship.

Josie became James Caan’s granddaughter.

Naming her Josie James created a clear tribute to Scott’s father.

For Kacy, becoming a parent therefore also meant joining a family with a complicated but deep Hollywood history.

James Caan Died in 2022

James Caan died on July 6, 2022, at age 82.

People’s family profile notes that his death was connected with heart-related health issues and describes the close bond he maintained with his children and grandchildren.

For Scott, the loss was obviously personal.

For Josie, it meant losing the grandfather whose name she carries as her middle name.

Kacy did not publicly turn the family’s grief into interviews.

That again fits her established pattern.

Major family events happen.

She simply does not make them into publicity.

How Old Is Kacy Byxbee?

Kacy’s exact date of birth is not strongly established in authoritative public sources.

Many celebrity biography websites give specific birthdays or ages.

Those numbers often appear without explaining where they came from.

Neither her IMDb biography nor the stronger reporting about her relationship with Scott provides a verified date of birth.

For that reason, assigning her an exact age in 2026 would risk repeating an unsupported claim.

This is a good example of why not every “fact” repeated across celebrity websites should automatically be copied.

Her age is less firmly documented than her career credits, relationship or daughter’s birth date.

Is Kacy Byxbee on Instagram?

Kacy does not maintain the kind of highly visible verified social-media presence associated with a celebrity influencer.

There are photographs of her online, particularly from red carpets and entertainment events.

But those images should not be confused with an official account.

Because Kacy’s public profile is limited, accounts using her name should be treated cautiously unless their authenticity is clear.

Her privacy is consistent with Scott’s approach as well.

The couple has never relied heavily on social media to explain their relationship.

That makes them somewhat unusual in an era when celebrity couples often share every major milestone online.

What Is Kacy Byxbee’s Net Worth?

Kacy’s personal net worth has not been independently verified.

Some websites publish precise estimates, but there is not enough reliable financial information to support them.

We know that Kacy worked professionally in costume and wardrobe.

We know that her Hawaii Five-0 credit covered dozens of episodes.

But that does not tell us her current assets.

We do not know her investments.

We do not know all of her property.

And Scott Caan’s money should not automatically be treated as Kacy’s personal net worth.

The accurate answer is therefore that her individual wealth is private.

Does Kacy Byxbee Have More Than One Child?

Only one child is firmly documented in reliable public sources: Josie James Caan.

E! reported her birth in 2014, and IMDb also identifies Josie as Kacy’s first child with Scott.

There is no need to create additional children based on unsourced family trees.

Josie is the publicly established daughter of Kacy and Scott.

Because she is still a minor in 2026, keeping unnecessary personal details about her out of celebrity coverage is appropriate.

The important fact is simply that Kacy and Scott became parents together in 2014.

Are Kacy Byxbee and Scott Caan Still Together?

This is one of the most searched questions about Kacy.

There has been no widely reported mainstream announcement of a breakup between them. Current biographical references continue to connect Kacy with Scott, though descriptions of their exact legal status vary.

Because both are private, absence of breakup news should not be turned into detailed claims about their everyday relationship.

The safest current description is that Kacy is Scott Caan’s longtime partner and the mother of his daughter.

There is no strong basis for inventing a separation.

There is also reason to be careful about claiming a specific wedding date when one has not been clearly documented.

Why Kacy Byxbee Still Attracts Interest

People initially search for Kacy because they know Scott Caan.

Then her own story becomes more interesting.

She did not meet Scott at a celebrity party after he became successful.

They were working on the same television series.

Scott was performing.

Kacy was helping make the production happen behind the scenes.

Their relationship developed while Hawaii Five-0 became one of CBS’s recognizable dramas.

Then they became parents.

That gives Kacy a genuine connection to Scott’s career rather than merely a celebrity-spouse label.

She was part of the production world herself.

Kacy Byxbee Built a Career Behind the Camera

This is perhaps the most important point to remember about Kacy.

Her public biography is short because costume work is rarely celebrated like acting.

Audiences see actors.

They do not always see the hundreds of people behind them.

Yet those crews make film and television possible.

Kacy’s credits on Somewhere, Hawaii Five-0 and All at Once establish that she had her own place within that system.

Her connection with Scott eventually became the reason mainstream entertainment outlets wrote about her.

But it was not the reason she was on a television set in the first place.

She was there to work.

Final Thoughts

Kacy Byxbee is often introduced simply as Scott Caan’s partner, but that description leaves out the beginning of her story.

She worked professionally in costume and wardrobe.

Her credits include Somewhere, All at Once and, most importantly, Hawaii Five-0. IMDb records her as a costumer across 69 episodes of the CBS drama from 2011 through 2014.

That show also connected her with Scott Caan.

Scott starred as Danny Williams, while Kacy worked behind the scenes. E! reported that the two met through the series and had already been together for several years by the time they welcomed their daughter.

Josie James Caan arrived on July 9, 2014.

Her middle name created a touching connection to her grandfather, legendary Godfather actor James Caan.

Over the years, Kacy and Scott occasionally appeared together at major entertainment events, including the Emmy Awards and film premieres.

But Kacy never transformed those appearances into a celebrity career.

She remained private.

Even today, basic details such as her exact birthday, education, current work and personal finances are not firmly established in dependable sources.

Those gaps are better left open than filled with invented facts.

What we do know already makes Kacy’s story interesting.

She worked behind the scenes of a major television show, met her longtime partner through that work, became a mother and joined one of Hollywood’s best-known acting families—all while maintaining a life that remains remarkably separate from celebrity publicity.
