Hilary Duff’s husband, producer Matthew Koma, is wading into the “toxic mom group” drama that’s taken the internet by storm. The controversy reared its head last week when former “High School Musical” star Ashley Tisdale published a damning essay for The Cut called “Breaking Up With My Toxic Mom Group.”Many on the internet speculated that Tisdale was referring to a mom group that included other celebrities, including Mandy Moore, Meghan Trainor and Hilary Duff. Though a rep for Tisdale told TMZ on Monday that Tisdale’s essay wasn’t referencing that particular mom group, Duff’s husband added some fuel to the fire with a pointed Instagram story on Tuesday. The producer superimposed his head over the photo of Tisdale used by The Cut to promote her essay, and changed the title to say “When You’re The Most Self-Obsessed Tone Deaf Person On Earth, Other Moms Tend To Shift Focus To Their Actual Toddlers.” “Read my interview with @thecut,” he wrote alongside the edited photo. He added the subtitle, “A Mom Group Tell All Through a Father’s Eyes.”Hilary Duff and Matthew Koma at Apple Music Studios on Dec. 4, 2025, in Los Angeles.Amy Sussman/Getty Images for Apple MusicHuffPost reached out to reps for Duff, Koma and Tisdale for further comment. In the essay, Tisdale wrote about feeling excluded from her group of mom friends over time. “I remember being left out of a couple of group hangs, and I knew about them because Instagram made sure it fed me every single photo and Instagram Story,” she wrote in her essay.“Another time, at one of the mom’s dinner parties, I realized where I sat with her — which was at the end of the table, far from the rest of the women. I was starting to feel frozen out of the group, noticing every way that they seemed to exclude me.” Tisdale said she ultimately sent a fiery text exiting the group once and for all. “This is too high school for me and I don’t want to take part in it anymore,” Tisdale said in a message to her fellow moms, which she admitted “didn’t exactly go over well.” Tisdale has not commented on the essay since it was published on New Year’s Day.
