Gigi Hadid and Zayn Malik's baby daughter's name has been revealed -- and was done in a subtle way.

While the couple remains close-mouthed about their baby, who was born in September, Gigi subtly dropped the name in her updated Instagram bio.

"Khai's mom," it now reads.

Earlier this week, Hadid shared various posts about her child, including a screenshot of a text message from Malik saying, "Hey ... I'm obsessed w our kid."

The new parents haven't shown Khai's face yet, but have shared glimpses of the baby in photos.

"Our baby girl is here, healthy & beautiful," Zayn tweeted after Khai's birth. "[T]o try put into words how [I] am feeling right now would be an impossible task."

"The love [I] feel for this tiny human is beyond my understanding," he added. "Grateful to know her, proud to call her mine, & thankful for the life we will have together x."
