Hilary Duff and Matthew Koma: A Complete Relationship Timeline

Hilary Duff and Matthew Koma don’t necessarily have the flashiest marriage in Hollywood—we don’t see them dominating the headlines in the way that some other couples do—but no one can say that these two aren’t willing to go to bat for each other. Even if that means posting headline-grabbing clap-backs to essays written by seemingly former friends.

Duff and Koma have been together since 2017, married since 2019, and have welcomed three daughters in addition to Duff’s son with ex-husband Mike Comrie. But their romance didn’t get off to the smoothest start; they were off and on a few times before they made the relationship stick for good. After all, these do seem to be pretty passionate people.

So let’s go back, back to the beginning. To the beginning of the Hilary Duff and Matthew Koma’s relationship timeline, that is.

January 2026: Koma calls out Ashley Tisdale for her personal essay in The Cut about a “toxic mom group” that seemingly included Duff.

In her essay, Tisdale described being excluded by the other members of the mom group and needing to end those friendships as a result. In a since deleted post, per The Hollywood Reporter, Koma responded with a parodic version of the article. The image had Koma’s face photoshopped onto Tisdale’s body, with the headline, “When You’re the Most Self Obsessed Tone Deaf Person on Earth, Other Moms Tend to Shift Focus to Their Actual Toddlers.” And subhead, “A Mom Group Tell All Through a Father’s Eyes.” He captioned the post, “Read my new interview with @TheCut.”

December 2025: Koma responds to speculation about the subject of Duff’s newest single, “Mature.” The internet has theorized that the song could be about Duff’s ex-boyfriend Joel Madden or even about Leonardo DiCaprio, who famously only dates women in their early to mid-20s.

In an Apple Music 1 interview with Duff, per E! News, Koma joked, “I think it could be about Bernie Sanders.”

May 3, 2024: Townes Meadow, Duff and Koma’s third daughter, is born. Wrote Duff on Instagram, “I have been dreaming of holding you in my arms for months and the past 5 days of getting to know you, stare at you and smell you has been pure moments of magic. We all love you like you’ve been here all along beauty.”

March 2021: Duff gives birth to the couple’s second daughter, Mae James. Duff included a photo from the home birth in her announcement on Instagram.

December 21, 2019: Duff and Koma tie the knot in an intimate ceremony in their own front yard, and the wedding is covered by Vogue. Duff wore Jenny Packham and carried the couple’s daughter Banks down the aisle.

May 9, 2019: Duff and Koma announce their engagement on their separate Instagram accounts. Both kept the messages simple. In her caption, Duff wrote, “He asked me to be his wife.” Koma, for his part, wrote, “I asked my best friend to marry me…”

October 29, 2018: Duff takes to Instagram to announce that she and Koma have welcomed a daughter. “Banks Violet Bair,” she wrote in the caption. “This little bit has fully stolen our hearts! She joined our world at home on Thursday afternoon and is absolute magic.”

December 2017: A few months after their breakup was reported, Duff confirms to The Talk that she and Koma are back together. “It’s going so great,” she said. “I mean, this is the third time that we’ve dated.”

March 2017: The couple break up, reportedly due to their mutually busy schedules, per E! News.

January 29, 2017: Duff and Koma make their red-carpet debut at Entertainment Weekly’s pre-SAG Awards party. Per Entertainment Tonight, this is shortly after Duff broke up with trainer Jason Walsh.

January 21, 2015: Koma and Duff have a business meeting, not knowing that it will lead to marriage and several children in a few years.

In a 2025 Instagram story posted to celebrate the couple’s wedding anniversary, Koma shared with fans a screenshot of the calendar event. Per E! News, it reads simply, “Hilary Duff Meeting.” He quipped in text, “The meeting went well!” Also in an IG story, Koma included a second screenshot of an email sent on that same day, from a friend who asked if Duff was “cool.” Koma replied, “I wanna get marriedb [sic].”

Duff herself went into a little more detail about the meeting in her Vogue interview from their wedding. Apparently, the lunch meeting lasted for two hours. “And then when we started talking about music, things started sparking and he was being funny enough, not flirtatious, but funny enough to where we started creating a banter and a nice friendship right off the bat,” she said.
