After Ashley Tisdale wrote an article about drama in her group of mom friends, people began to speculate that she was writing about Mandy Moore and Hilary Duff. The actor — who now goes by her married name, Ashley French — was in a friend group with them. Duff’s husband, Matthew Koma, seemed to confirm the rumors when he posted an image parodying the article. Shortly afterward, Moore posted praise about Koma.

Hilary Duff’s husband shaded Ashley Tisdale after she published an essay

In an essay for The Cut, French wrote about breaking up with her “toxic mom group.” While she described the women as “mean girls,” she did not identify any of them by name. Despite this, many have speculated that she was writing about a group that included Moore, Duff, and Megan Trainor. 

A rep for French denied this. Duff’s husband, Koma, fueled the rumors when he appeared to respond to the essay. In a photo posted to his Instagram Stories, Koma mirrored French’s pose from the image accompanying the essay. The headline on the image reads: “When You’re the Most Self Obsessed Tone Deaf Person on Earth, Other Moms Tend to Shift Focus to Their Actual Toddlers.”

“Read my new interview with @thecut,” Koma wrote. 

Mandy Moore showed love for Hilary Duff’s husband

On Wednesday, Jan. 7, Koma performed at “A Concert for Altadena,” a benefit for those impacted by the California wildfires in 2025. Moore’s home burned down in the fires, and she had to stay with Duff and Koma for a time.

“@matthewkoma happens to be one of the most talented and generous humans I’m lucky to know,” she wrote over a video shared to her Instagram Story. “He literally gave my family a place to stay one year ago today when we evacuated. Love you, MB!!”

Notably, French’s response to the wildfires was allegedly part of the reason for the rift in the friend group.

“It wasn’t an overnight thing. Her politics don’t align with a lot of the group members, which drove a wedge between them,” the source told the U.S. Sun. “But the big straw that broke the camel’s back was how Ashley responded to the group about the LA wildfires last year. Multiple members of the group were impacted, some worse than others, and Ashley hardly checked in.”

Mandy Moore said Hilary Duff founded the friend group

Moore and Duff have known each other for years, and they grew close after both having children.

“Hilary is the coolest and she is a super-mom. She and Matt have become really close friends with my husband and I,” she told InStyle in 2022. “But they have a kid who’s six weeks younger than Gus. And so, we had babies at the same time and she, being the super-mom that she is, formed a cool mom club.”

Moore and Duff had similar career trajectories. They both rose to fame in their teens with music and acting careers, and have continued to act into adulthood.
