Ali Larter and Husband Hayes MacArthur’s Relationship Timeline

Ali Larter and her husband, Hayes MacArthur, have been by each other’s side for two decades.

The pair first crossed paths in 2005 while filming the movie Homo Erectus and went on to pursue a relationship.

“I told my boyfriend after three weeks that I wanted to marry him and that we could do it tomorrow,” Larter told Cosmopolitan in 2007. “I look forward to that time when I’m home with babies.”

Larter and MacArthur announced they were engaged in 2007. “Since I was 15 years old, all I wanted was to find the guy I was going to marry. My heart got broken so many times because I put so much pressure on it. And then … I got blindsided,” she told Cosmopolitan in 2009. “[He] showed me the way, and all was right. This is how it’s supposed to be.”

Us Weekly confirmed in 2009 that Larter and MacArthur tied the knot in an intimate ceremony at his parents’ home in Kennebunkport, Maine. The couple went on to welcome son Theodore in 2010 and daughter Vivienne in 2015.

Larter explained to Us how she and MacArthur maximize their date nights as parents of two. “We like to walk to dinner,” Larter said. “We love to go out and get pasta and a beautiful bottle of wine and just take our time. We don’t want to just rush to a restaurant and rush to eat. It’s really about getting off the clock.”

Larter added that she sees qualities of herself and MacArthur in her kids. “Teddy’s like me because we run hot, we definitely have a little temper and it takes us a minute to simmer down,” she said. “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.”

2020

During the COVID-19 pandemic, Larter and MacArthur moved their family from Los Angeles to Idaho.

Larter exclusively told Us that she never imagined she would end up in Idaho. “It unfolded in the most incredible way for us,” she said. “If you had told me this 20 years ago, even five years ago, I would have never believed that I’d be living in a very small town in the mountains.”

She continued, “We absolutely adore it, and we are so grateful to get to raise our family here. It’s really, really beautiful to live a smaller life with our children during this chapter.”

January 2025

Larter reflected on her and MacArthur’s move to Idaho during a January 2025 appearance on Live With Kelly and Mark.

“Our kids’ schools were shut down during COVID and we were like, ‘Why are we just sitting here?’ It was not working at all in Los Angeles,” Larter said during the episode. “So, my husband said, ‘Let’s take a road trip to Idaho [and] go skiing with the kids.’”

The getaway trip turned into a longer stay. “We fall in love with nature and the mountains and this entire new life,” she gushed. “We totally pivoted and went for it. We literally had our house [in California] for less than a year. We went back to L.A. and we realized we wanted to put our family first.”

Larter continued, “Our life is so different there and it’s a small town, and it kind of holds you to a different type of accountability. It’s something that me and Hayes really wanted to do for our children, so we did.”

Larter explained that the family has “a real life” that is “rooted in reality” after relocating to Idaho.

“We’re so grateful,” Larter said, later joking that Theodore initially wasn’t pleased with the idea. “He likes fast cars and designer colognes and that whole thing, like, he wants to be in the big city. I’m like, ‘At 18, you can go [back].’ … He really likes it now and I think he understands how great his wolf pack is there.”

Larter added that she and MacArthur “feel if you can hike a mountain, you can run a boardroom.” She concluded, “We just believe in raising them that way.”
