Gigi Hadid finally revealed the name of her baby daughter whom she shares with boyfriend Zayn Malik.

The 25-year-old supermodel subtly changed her Instagram profile to read "Khai's mom."

The couple welcomed Khai in September and have kept her face off of social media.

"Our baby girl is here, healthy & beautiful," Malik, 28, tweeted on Sept. 23. "To try put into words how I am feeling right now would be an impossible task."

Hadid shared a black-and-white photo of her daughter's hand and wrote, "Our girl joined us earth-side this weekend and she's already changed our world. So in love."
