Ali Larter’s Marriage Faces Clear Challenges: Here’s What We Know

Ali Larter’s intriguing real-life marriage to actor and comedian Hayes MacArthur has become a topic of fascination. Their story includes a whirlwind romance, a rumored quick breakup, and an unexpected move from Los Angeles to the rural town of Sun Valley, Idaho, during the peak of the COVID-19 pandemic. Their ability to balance their bustling family life with their careers only adds to the public’s interest.

The couple’s journey began in 2005 on the set of the R-rated comedy “National Lampoon’s Homo Erectus,” hardly the setting for romance. Yet, Larter quickly realized MacArthur was the one. “I told my boyfriend after three weeks that I wanted to marry him and that we could do it tomorrow,” she revealed to Cosmopolitan in 2007, as reported by People.

Larter’s instincts proved correct, as their marriage has spanned over two decades, with two children, Theodore and Vivienne. “He’s so funny, and he’s an amazing father, and we just — we keep doing it. We keep growing together,” she told Barrymore. Nonetheless, Larter acknowledged the challenges of long-term commitment, adding, “But we love our family, and we learn from each other every day, and I’m grateful for that.”

In a bold move during 2020, at the height of the pandemic, Larter and MacArthur decided to leave Los Angeles. Their destination was somewhat spontaneous. “We figured it was an opportunity to go on an adventure as a family. And we just started driving north,” Larter explained to People in September 2024, describing the couple’s unusual relocation to Idaho.

Fortunately, it appears Larter’s instincts were right, as the couple has been married for more than 20 years and share two children together, Theodore and Vivienne. “He’s so funny, and he’s an amazing father, and we just — we keep doing it. We keep growing together,” she gushed to Barrymore. Still, Larter was careful to note that long-term relationships are never easy. “But we love our family, and we learn from each other every day, and I’m grateful for that,” she added.

Idaho or bust?! In 2020, during the height of the COVID-19 pandemic, Ali Larter and Hayes MacArthur made the abrupt decision to pack up their family and hightail it out of Los Angeles. The destination? Unknown — well, sort of. “We figured it was an opportunity to go on an adventure as a family. And we just started driving north,” Larter told People in September 2024 about the couple’s unconventional move. 

Still, it appears the couple had some idea of what they were looking for. “We wanted to go to a ski town because we wanted to be able to be outside with our family when you couldn’t be inside or wear masks,” Larter told host Amanda Hirsch during an interview on the “Not Skinny but Not Fat” podcast. “We drove in Idaho, and we made this choice,” she said about landing on Sun Valley, Idaho.

Fast forward years later, and the family is still thriving in the small ski town. “Neither of us had ever lived in a small town before,” Larter told People. “People look out for each other. There’s a real sense of community here, and we’re so happy to be a part of it.”

Speaking of unconventional, Ali Larter and Hayes MacArthur’s version of family life is a little different from most, especially given their busy careers in the entertainment business. “I brought my kids to the set of ‘Pitch’ the other morning because when you’re working crazy hours, you have to find the time,” Larter confessed to People in October 2016. At the time, the couple’s children, Theodore and Vivienne, were five and a half and 21 months, respectively.

According to Larter, she and MacArthur do a lot of tag-teaming when it comes to rearing their kids. During a November 2025 interview with People, she revealed she was away from her family for five months that year while shooting “Landman.” And that’s when her husband, whom she refers to as her “support system,” comes in. “And then when he leaves, I can hold down the fort,” she explained about their divide-and-conquer dynamic. “He’s my rock,” the Landman star gushed about her real-life partner. Hey, whatever works.
