The sweet snap is simply captioned, "baby daddy," with a smiley face emoji. This is the first photo that Hadid has posted with her boyfriend since she celebrated her 25th birthday in April, and since sharing her pregnancy news.
Last month, a source told ET that the couple is "excited to welcome their daughter very soon."
"Gigi has been enjoying pregnancy and everyone around her knows she'll be the best mom," the source said. "Gigi publicly hasn’t shared much because she knows now is not the time to share everything as there is much more important things going on in the world like coronavirus and BLM. Gigi feels her platform is better used to highlight and bring awareness to those things right now."
"Gigi hasn’t been private with family and friends," the source added. "She’s documented everything and shares photos and her progress with the people around her.”
"Everyone's like, 'Oh, you didn't look pregnant in your jumpsuit on your last Live.' That's because this way [front on], I'm going to look normally how I look in this," Hadid said, before revealing her bare baby bump under her top. "The reason I say it's a different story is like... there's my belly, y'all. Like, it's there. It's just that, from the front, it's different. You know what I mean?"
In a previous tweet, the California native also explained how she would "share 'insight'" on her pregnancy when she feels like it.
"For now I am proudly experiencing and sharing this time with my family and loved ones," she wrote.
