The supermodel and singer have been very private about their first child

Gigi Hadid finally revealed the name of her and boyfriend Zayn Malik's 4-month-old daughter!

The couple's precious first born is named Khai.

The supermodel, 25, did not make a big announcement but instead subtly changed the bio of her Instagram account to include "khai's mom."

The change on her profile comes a day after she shared several gushing posts about her child on Wednesday, including a screenshot of a text message from Malik, 28, saying "Hey ... I'm obsessed w our kid."

Hadid and Malik have yet to show a picture of Khai's face, but they've shared little glimpses of her in photos.

The secrecy is in line with the supermodel's pregnancy as she didn't share photos of her baby bump until August, a month before giving birth in September.

The new mom and "Better" singer shared the news of their daughter's arrival in separate social media posts.

"Our baby girl is here, healthy & beautiful," Malik tweeted on Sept. 23 alongside a photo of the baby holding onto his finger. "to try put into words how i am feeling right now would be an impossible task."

 The former One Direction member added, "The love i feel for this tiny human is beyond my understanding. Grateful to know her, proud to call her mine, & thankful for the life we will have together x."

Months later, Hadid revealed to fans that she found out she was pregnant "the day before the Tom Ford show" during Paris Fashion Week.
