Who Is Kacy Byxbee? Inside the Quiet Life of Scott Caan’s Longtime Partner
If you’ve spent any time on a Hawaii Five-0 fan forum or scrolled through old red-carpet galleries, you’ve probably come across the name Kacy Byxbee and wondered who she actually is. She’s not a household name in the way her partner’s family is, but that’s kind of the point — Kacy has built a career and a life largely away from the spotlight, even while being connected to one of Hollywood’s most recognizable acting dynasties.
This article breaks down everything publicly known about her: her behind-the-scenes work in television, her relationship with actor Scott Caan, her family life, and why she’s remained such a private figure despite years of public curiosity.
Who Is Kacy Byxbee?
Kacy Byxbee is an American costume and wardrobe professional best known for her work on the hit CBS series Hawaii Five-0. She’s often described in tabloids simply as a “model,” but her actual career has been rooted in production — specifically in costume departments on film and television sets.
She’s most widely recognized, however, as the longtime partner of actor Scott Caan, son of the late Hollywood legend James Caan. That connection has made her a recurring subject of entertainment coverage, even though she herself has never sought that kind of attention.

Career in the Costume and Wardrobe Department
Long before she became a subject of tabloid curiosity, Kacy was quietly working her way through the production side of the entertainment industry. She got her start in costume work on Sofia Coppola’s 2010 film Somewhere, serving as part of the wardrobe team. That same year, she began working in a similar capacity on Hawaii Five-0, the CBS procedural that would go on to run for ten seasons.
According to available records, she worked in the Hawaii Five-0 costume department from roughly 2011 to 2014, a stretch that overlapped with the years she and Scott Caan — who starred on the show as Detective Danny “Danno” Williams — became a couple. She’s also credited on the 2016 film All at Once.
It’s worth noting that costume department work is genuinely demanding: it involves everything from sourcing wardrobe pieces and managing continuity between scenes to fitting actors and coordinating with the show’s broader production design. It’s not a glamorous, front-facing job, and that seems to suit Kacy’s personality — she’s built a career on being useful on set rather than being seen.
Why Her Career Rarely Gets Discussed
Because most coverage of Kacy Byxbee focuses on her relationship, her actual professional background often gets flattened into a single line — “costume designer” or “model” — without much context. In reality, her work on a hit network drama for several years represents a legitimate industry career, even if it’s not one she’s publicized herself.
Kacy Byxbee Age
One of the more common questions people search for is kacy byxbee age, but here’s the honest answer: there’s no verified, publicly confirmed birth year for her. Some celebrity-trivia sites list her birthday as January 24 and note she’s an Aquarius, but none of the more credible entertainment or biography sources have published a confirmed birth year, and Kacy herself has never addressed it publicly.
Given how private she’s kept her personal life—no active public social media presence, no interviews about her upbringing—it’s likely intentional that details like her exact age haven’t circulated widely. If a reliable source ever confirms a verified figure, this section can be updated accordingly.
Relationship With Scott Caan
Kacy Byxbee and Scott Caan have been together for well over a decade, though neither has confirmed an exact start date. Public appearances suggest the relationship has been steady and long-term, playing out largely through red-carpet events rather than interviews or social media posts.
The two have been photographed together at a number of industry events over the years, including:
- The Hawaii Five-0 Season 7 “Sunset on the Beach” premiere event
- The 4th Annual CBS Television Studios Summer Soiree in West Hollywood (2016)
- The Tribeca Film Festival screening of Untogether in 2018
- The Los Angeles premiere of Entourage in 2015
Scott Caan has spoken about her sparingly in public, but in one notable moment on Chelsea Lately back in January 2013, he described her as an easygoing, low-maintenance partner — the kind of light, affectionate comment that gave fans one of the few direct glimpses into their relationship from his side.
Connection to the Caan Family
Because Scott Caan is the son of James Caan — star of The Godfather, Misery, and Elf — Kacy’s relationship with Scott has naturally put her in proximity to a well-known Hollywood family. She’s never leaned into that association publicly, though, and there’s little indication she’s tried to use the connection to build her own public profile.
Kacy Byxbee Daughter
In 2014, Kacy and Scott welcomed their first child together, a daughter named Josie James Caan, born on July 9, 2014. The middle name is a clear nod to Scott’s father, James Caan, tying together three generations of the family.
Search interest in kacy byxbee daughter tends to center on basic details — her name, birth year, and general background — but true to form, the family has kept details about Josie’s upbringing almost entirely out of the public eye. There are no confirmed public appearances of Josie beyond occasional, brief mentions in older entertainment coverage, and neither parent has used their platforms to share updates about her.
That kind of restraint isn’t unusual for industry families who work primarily behind the camera rather than in front of it, but it does mean fans looking for more detailed updates on Josie’s life are unlikely to find much beyond the basic facts of her birth.
Why Kacy Byxbee Stays Out of the Spotlight
It’s fair to say Kacy Byxbee represents a different kind of “Hollywood partner” than what most people expect. She doesn’t run a public Instagram brimming with red-carpet photos, she doesn’t give tell-all interviews, and she hasn’t tried to parlay her relationship into her own media career. Instead, she’s kept working in production roles and largely let her relationship with Scott Caan speak for itself through occasional public appearances.
This approach has, somewhat ironically, only fueled more curiosity. When someone maintains genuine privacy in an industry built on visibility, people tend to want to know more, not less. That’s part of why searches like “kacy byxbee age” and “kacy byxbee daughter” remain fairly common — there’s a public information gap that her own choices have created.
Final Thoughts
Kacy Byxbee’s story is really a story about two different lives running in parallel: one as a working costume and wardrobe professional who put in real time on a major network show, and another as the quietly private partner of a well-known actor from an even more well-known Hollywood family. She hasn’t confirmed her exact age, she’s kept her daughter’s life almost entirely private, and she’s never seemed particularly interested in being a public figure in her own right.
For fans who are curious, that’s likely to remain the shape of her public story going forward — glimpses at industry events, a name attached to a beloved show’s credits, and very little else volunteered. And honestly, given how much of Hollywood runs on oversharing, there’s something almost refreshing about that.
