How Old Is Hilary Duff's Son? Meet Luca, Banks, Mae & Townes

The Direct Answer: How Old Are Hilary Duff's Kids?

The short answer to 'how old is Hilary Duff's son": Luca Cruz Comrie is 14 as of October 2026. But Luca is one of four — Duff's household is a blended family with a 12-year age span from eldest to youngest.

Duff married singer-songwriter Matthew Koma in December 2019, after her 2010–2016 marriage to NHL player Mike Comrie ended in divorce. She co-parents Luca with Comrie — 'Mike and I are a team. We will always be a team," she has said — while raising her three daughters with Koma.

Luca Cruz Comrie (Age 14)

Luca Cruz Comrie, Duff's first child and only son, was born on March 20, 2012. He is 14 years old as of October 2026. Duff welcomed him with then-husband Mike Comrie, the former NHL player she married in 2010 and divorced in 2016.

Luca has grown up partly in the public eye — Duff has described him as kind, caring, and fiercely protective of his younger sisters. At Duff and Koma's wedding, Luca read a poem he wrote for the occasion, calling their family 'a galaxy shooting off into the cosmos' — a line that tells you everything about his place at the center of this blended family.

Now a teenager, Luca is old enough to have watched his mother go from Disney Channel star (Lizzie McGuire, 2001–2004) to sitcom lead (How I Met Your Father) to mother of four. Duff has spoken about the 'wild choice' of having four kids, and Luca — the original kid — has been there for all of it.

Luca's fourteenth birthday in March 2026 marked another milestone: Duff celebrated with a Disneyland trip and a tribute post marveling at how fast the years went. At 14, he is now older than Duff was when Lizzie McGuire premiered — a fact that tends to stop millennial fans cold. He has grown up alongside his mother's second act, from her music comeback to her new album era in 2026.

Banks Violet Bair (Age 7)

Banks Violet Bair was born on October 25, 2018. She is 7 years old as of October 2026 — Duff's first child with Matthew Koma, arriving about a year before their wedding.

Banks is reportedly a music lover like both her parents — Duff has shared that Banks is a fan of her mom's music as well as Harry Styles, and was once spotted at a Styles concert with an awe-filled expression. She has developed a close bond with her big brother Luca, who is famously protective of her.

As the eldest of the three Koma daughters, Banks has watched her family double in size: she was an only sister for two and a half years before Mae arrived, and now she's the middle child of the girls' trio.

As the eldest of the Koma girls, Banks occupies a special role: old enough to remember when it was just her and Luca, young enough to still be a kid herself at 7. Duff has shared that Banks adores performing and music — unsurprising with a pop-star mother and a musician father — and the Harry Styles concert story suggests the performance gene is expressing itself early.

Mae James Bair (Age 5)

Mae James Bair was born on March 24, 2021, via a water birth at the couple's home. She is 5 years old as of October 2026.

Duff has described Mae as a humorous child who loves to jump and is always trying to befriend her older sister Banks. The home water birth was a deliberate choice the couple repeated — when Townes arrived three years later, it was also a home water birth, suggesting the experience with Mae had been a positive one.

Mae's arrival in spring 2021 made Duff a mother of three, and the family settled into a rhythm of two girls under three — the calm before the fourth baby.

Townes Meadow Bair (Age 2)

Townes Meadow Bair, the youngest, was born on May 3, 2024 — also via home water birth. She is 2 years old as of October 2026.

Duff announced the pregnancy in December 2023 with the family's Christmas card: "Buckle up Buttercups, we're adding one more to this crazy bunch!' When Townes arrived, Duff posted black-and-white photos from the birth on May 7, 2024, writing: 'Townes Meadow Bair, now we know why she made us wait so long… She was perfecting those cheeks! I have been dreaming of holding you in my arms for months and the past 5 days of getting to know you, stare at you and smell you has been pure moments of magic. We all love you like you've been here all along beauty. 5/3/24.'

With Townes, the Duff-Koma household became six — and Duff has embraced the chaos publicly, writing that '4 kids is a truly wild choice' and crediting Koma for making it work.

A Blended Family That Actually Works

What sets the Duff family apart from a standard celebrity-kids rundown is the blended-family mechanics. Luca splits his life between two households, and Duff has been open about making that work: 'Mike and I are a team. We will always be a team.' It's a co-parenting posture she repeats in interviews, and by all public accounts, it holds — Luca is described as close to both his mother and his stepfather.

Duff likes the chaos. 'I like it when there are a lot of energetic people at home and the house is so full of life," she has said of the six-person household. The age spread — 14 down to 2 — means the family contains a teenager, a school-age kid, a preschooler, and a toddler simultaneously, each in a completely different phase.

As of October 2026, the family is also navigating Duff's pop comeback — new music and her first tour in a decade — with four kids at home. It's the latest chapter for a star who has been famous since childhood and is now raising children of her own, on her own visibly joyful terms.

Four Kids, Two Households, One Team

The mechanics of Hilary Duff's family deserve a closer look, because blended families this visible are rarely this functional — at least in public. Luca, 14, splits his life between his mother's household and his father Mike Comrie's, while Banks (7), Mae (5), and Townes (2) live full-time with Duff and Matthew Koma. Making that work across a 12-year age span takes deliberate effort, and Duff talks about it with unusual frankness.

Her co-parenting mantra — 'Mike and I are a team. We will always be a team' — is backed by more than a decade of practice. Duff and Comrie divorced in 2016, when Luca was 4; ten years later, the arrangement has produced a teenager who wrote a poem calling his blended family 'a galaxy shooting off into the cosmos' at his mother's wedding. That is not the output of a broken system.

On the Koma side, the partnership looks equally deliberate. When Duff announced the fourth pregnancy via the family's 2023 Christmas card ('Buckle up Buttercups, we're adding one more to this crazy bunch!'), she paired it with a tribute to Koma, writing that '4 kids is a truly wild choice' and crediting him with making it work — including handling the kids solo after late nights so she could sleep. As of October 2026, with Duff mounting a pop comeback and tour while running a six-person household, the team structure is being stress-tested in real time — and, by all public evidence, holding.
