Back in January 2017, the pair confirmed their budding romance by posing on the red carpet together at Entertainment Weekly's pre-SAG Awards party at Chateau Marmont. 

Shortly after their red carpet debut, a source confirmed to E! News the two had split in March 2017. According to the source, the breakup was triggered by their busy schedules. 

By October 2017, they had rekindled their romance, evidenced by his appearance at her 30th birthday party. "Since Matt got back from tour, they've been seeing each other again," a source told E! News exclusively at the time. "Him being gone on tour was the main reason things didn't work out the first time around, so now that he's back, they picked up right where they left off." As she later revealed on The Talk in December 2017, it was actually the third time they were dating. "Timing is such a big deal… third time's a charm!" she told the co-hosts. 

In June 2018, the couple has sweet news to share: they had a baby girl on the way. "We made a baby girl!" Koma wrote on social media. "She will be as beautiful and sweet as her mother...@hilaryduff another incredible chapter begins."

By the fall, they officially added a new member to the family: daughter Banks Violet Bair. "This little bit has fully stolen our hearts! She joined our world at home on Thursday afternoon and is absolute magic," the actress shared online in October 2018. 

Nearly two years after stepping out publicly for the first time, Koma asked the actress to marry him. 

Duff and Koma said "I do" in Dec. 2019, surrounded by their loved ones! 

When celebrating his one year wedding anniversary to Hilary, Matthew wrote a thoughtful post on Instagram expressing his gratitude for all that she's done during the pandemic. "I'm so in awe of your badassery," he gushed in part. 

Hilary and Matthew went on to welcome daughter Mae James Bair in March 2021.
