The two have been spending time together at Hadid's farm throughout the pandemic, and Gigi just shared a photo of the couple kissing with the caption "baby daddy."
After speculation surrounding Gigi's 25th birthday, she confirmed that she was pregnant in May — and is now around 7 months along.
"I think a lot of people are confused why I'm not sharing more," Gigi said during a livestream in July, "but I'm pregnant through a pandemic. Obviously, my pregnancy is not the most important thing going on in the world."
Plus, the pair is usually pretty private — Gigi only confirmed that the couple were back together on Valentine's Day, after months of speculation.
There we have it: Best of luck to the happy couple!
