After dating on and off for several years, Koma and Duff welcomed their first child together, Banks, in October 2018. Just months later, the pair got engaged.

In an interview with Vogue at the time, the actress revealed that Koma popped the question near their New York City apartment in a park.

"I'd had a very long day. I think my call time that morning was 4 a.m., and by the time I got home, our daughter was already asleep," she told the magazine at the time, revealing that her now-husband handed her a notebook filled with drawings of the two of them.
