Ali Larter has always been one of Hollywood's most quietly captivating figures — but on Friday evening in Los Angeles, it was her 11-year-old daughter Vivienne who nearly stole the show.
The Landman star, 50, joined Vivienne Margaret MacArthur at Step Up's 2026 annual Inspiration Awards at the Skirball Cultural Center, marking one of the youngster's most high-profile red carpet appearances to date. Standing nearly shoulder to shoulder, the resemblance between mother and daughter was almost uncanny — both blonde, both radiant, and both utterly at ease in front of the cameras.
A Mother-Daughter Moment Worth Celebrating
Larter cut an elegant figure in a navy pantsuit paired with a chocolate brown camisole featuring delicate lace detailing around the neckline. She wore her long blonde hair in soft waves and accessorised with silver hoop earrings and stacks of sparkling bracelets. Vivienne coordinated beautifully alongside her mum in a navy spaghetti-strap mini dress, finished with black trainers with pale pink laces.
The pair wrapped their arms around one another on the red carpet, sharing a sweet moment when Vivienne dissolved into laughter as her mum affectionately placed a hand on her head. Also in attendance at the event — which celebrates Step Up's work mentoring girls and young women — was Larter's Landman co-star Demi Moore, who brought her own daughter, Tallulah Willis.
"My daughter is so funny. She giggles at herself, she laughs at everything, and she's very similar to my husband in that way. Just totally the most fun person to be around."
The Bond Behind the Glamour
Despite the striking physical similarities between the two, Larter has previously revealed that Vivienne's personality actually mirrors that of her husband, Hayes MacArthur, 49 — the comedian and actor she met on the set of National Lampoon's Stoned Age in the early 2000s and married in 2009. The couple are also parents to 15-year-old son Theodore, known as Teddy.
For Larter, even the most ordinary routines have become an opportunity to nurture their relationship. "I have a daughter and you kind of make it like it's like a beautiful part of your night instead of it being rushed," she told People, reflecting on how motherhood has reshaped her approach to everything from her skincare regimen to her evenings at home.
Life Beyond Hollywood
Friday's outing was a relatively rare one for the family, who traded Los Angeles for Sun Valley, Idaho, during the Covid-19 pandemic and never looked back. What began as a road trip became a permanent relocation after the couple fell in love with the mountain town's slower, tighter-knit way of life.
"We went back to L.A. and we realised we wanted to put our family first. Our life is so different there and it's a small town, and it kind of holds you to a different type of accountability."
The move has clearly paid dividends for the children, too. "We love raising our kids there — they're kind of free-range," Larter has said. "My daughter can take the bus on her own. It's small and safe, and it's building the kind of character we want for them — patience, kindness, love of nature."
It is a grounded, deliberately unglamorous existence for someone who has enjoyed a significant career resurgence of late. Larter currently stars as Angela Norris opposite Billy Bob Thornton in Taylor Sheridan's hit series Landman, a role that has reminded audiences just how compelling a screen presence she is. Yet by her own account, the school runs, the Sunday barbecues, and the soccer touchlines in Idaho matter just as much — if not more.
"I'm cooking dinners and allowing myself to sleep in, or going to yoga or taking long hikes with the dogs," she told People. "And I'm at every soccer game and every soccer practice, and that really feeds me."
If Friday's red carpet was anything to go by, Vivienne MacArthur is growing up fast. Something tells us we'll be seeing a great deal more of her.
