Ratajkowski tied the knot with Bear-McClard in February 2018. In an essay on pregnancy in 2020 for Vogue, she revealed the couple didn't want to know the gender of their baby until they turned 18, adding "they'll let us know then".

"I like the idea of forcing as few gender stereotypes on my child as possible," she wrote. "But no matter how progressive I may hope to be, I understand the desire to know the gender of our fetus; it feels like the first real opportunity to glimpse who they might be."
