Duff was first linked to Koma in early 2017. They broke things off in March, but reconciled later that year.

The couple announced they were expecting in June 2018 and welcomed daughter Banks Violet Bair, now 2, that October. (Duff also shares son Luca Cruz, 8, with ex-husband Mike Comrie.)

Duff and Koma tied the knot on Dec. 21, 2019 in a backyard ceremony held at their Los Angeles home. A source told PEOPLE at the time that the affair was "small and low-key" with only family and friends present.

"The ceremony started at sunset and they got married inside the house. When the ceremony was over, guests cheered. The reception was in a white tent in the backyard," the source said. "Her sister Haylie was very involved in the wedding prep too. Hilary and Haylie are very close."

The intimate nuptials came just seven months after the pair had announced their engagement.
