But Koma’s food baby didn’t stand a chance against Duff and her bump. She captioned the snap, “I win,” because, ya know, she’s growing a tiny human in there.

The Younger star and Koma announced they’re expecting their first child together early last month and have yet to reveal when their little girl will arrive. This will be Duff’s second child—she shares 6-year-old son Luca with her ex, Mike Comrie—and Koma’s first.

Sorry, Koma. Duff definitely won this installment of “Who Wore It Best?—Baby Bump Edition.”
