Hilary Duff & Matthew Koma’s Relationship Timeline Is What Dreams Are Made Of

For many people, Hilary Duff’s life is what dreams are made of. The Disney alum has grown from the always relatable Lizzie McGuire to sitcom star, mother of three kids, and wife to musician Matthew Koma. With the second season of her latest show, How I Met Your Father, dropping on Jan. 24, viewers will likely be curious about her love life in 2023. Duff and Koma’s relationship timeline shows just how far these two have come, going from collaborating on music to celebrating three years of becoming Mr. and Mrs.

Duff and Koma met in 2015, when Koma worked with the “Come Clean” singer on her 2015 album Breathe In. Breathe Out. The pair didn’t start dating right away, but they had an instant connection. “They had great chemistry in the studio,” a source close to Duff told Us Weekly in 2017. “Hilary thinks Matt is very talented and cute.” Over seven years later, they’re standing strong as husband and wife.

After making their romance official in 2017, the couple got engaged in May 2019 before tying the knot that December. Now, Duff and Koma have two daughters together, 4-year-old Banks Violet Bair and 1-year-old Mae James Bair, joining Duff’s 10-year-old son Luca, who she had with her ex-husband Mike Comrie. With any luck, Duff will work with her husband on new music again at some point, making their relationship a full-circle moment.

After she changed into sweatpants, Koma took her to a “gorgeous park” and gave her a book he had been making for the occasion. “He’s like ‘It’s our story,’ and he had this amazing guy, Shane, do all of these illustrations,” she said. “He was like, ‘We are going to forget things along the way so we need to constantly fill this out so our kids can know our story.’” Little did Duff know that there was a surprise waiting on the last page: her engagement ring. “He got down on one knee and he’s like, ‘I forget everything I’m supposed to say but you’re my best friend.’ It was so sweet,” she remembered.

Our life is so full and I’m over the top grateful for the guy that I got to do all this madness with.”

Meanwhile, Koma also posted on his account saying, “We crushed 3 years @hilaryduff. Anyone who says marriage is easy, hasn’t been married or is raging slightly too high a microdose. But the work is the best part.” In keeping with their humor, he added, “Thank you for raising our very cute and very unstable three kids. Thank you for being so hot and letting me do things to the body. It’s so sick.”
