Matthew Koma knows how to pay wife Hilary Duff a compliment.
“6 years my wifey. And they said we wouldn’t make it. Literally everyone said, ‘They won’t make it.’ OK just that guy in the Just Jared comment section but f*** him we’re crushing. Being married to you is like eating Taco Bell in the late 90’s,” Koma wrote via his Instagram Story on Sunday, December 21, alongside a photo of the couple cutting cake at their wedding.
He continued, “I never know which you I’m gonna get but it’s largely the same ingredients and the euphoria outweighs the tummy discomfort. And you always look cool and I get really excited when someone says, ‘We’re going to get a meximelt.’ I love you, our kids are screaming at each other and Mae just ripped a Ken doll’s head of.”
Duff, meanwhile, reposted the message via her own Instagram Story on Sunday, writing, “It’s so hot being compared to Taco Bell. He always gets the assignment.”
Koma went on to share a screenshot of a meeting with Duff in his calendar from 2015, writing, “The meeting went well!”
In another snap, Koma uploaded a screenshot of his reaction after meeting Duff, where he wrote in an email about her, “I wanna get marriedb [sic].” Koma added in his Instagram Story, “And I did,” to which Duff wrote on Sunday, “Haahahahaha dork!”
Duff and Koma welcomed daughter Banks in 2018, one year before they tied the knot. The couple have since welcomed daughters Mae and Townes in 2021 and 2024, respectively. (Duff also shares son Luca, born in 2012, with ex-husband Mike Comrie.)
The pair have since given fans glimpses of their romance. While celebrating their five-year wedding anniversary in December 2024, Duff shared a photo of Koma and wrote, “Five years down. Forever to go.”
Koma, meanwhile, called Duff his “dream girl” and “best friend” in his own tribute.
“As I lay next to you in bed, purely exhausted after our third consecutive 14 hour day of taking our 4 kids skiing — I feel like the luckiest. You chose me to do the impossible with,” he wrote, in part. “And as we navigate through the truly IN IT years, I think the most exciting thing is knowing on the other side of this, we get each other. You’re my favorite person to do absolutely anything and everything with.”
He continued, “And I know that may sound underwhelming considering my inability to tolerate the majority of humans, but you light this grinch up in a way that forces me to fully submit and coast closer to the #LiveLaughLove sun than I ever thought possible.”
Duff has since announced a return to music, with Koma by her side. In November, Duff dropped her single “Mature,” which she cowrote with Koma and Madison Love. (She went on to reveal that her latest full-length album, Luck … Or Something, will drop on February 20, 2026.)
“‘Mature’ is out today,” Koma wrote via Instagram at the time. “It’s the first song ya’ll are hearing from an album my wife made over the last year and a half. Talk about an exercise in reclaiming what’s yours, giving yourself the license to step into a voice your younger self didn’t get to have, and doing it completely, unapologetically on your terms.”
He continued, “Ba, I hope the world loves this song, loves your album, and gives you all the flowers you deserve – but I simultaneously don’t really give a fuck what anyone thinks because we got to make something YOU love, that you think is rad, and we got to do it together — the rest is a bonus. Congratulations to my sweet wife, you’re the f****** coolest.”
