Zayn Malik and Gigi Hadid reveal they've welcomed their baby in adorable new photo

Former One Direction star Zayn Malik and Gigi Hadid have welcomed their baby into the world

Sharing a sweet photo of their "tiny" baby girl holding her father's hand, Zayn wrote on Twitter: "Our baby girl is here, healthy and beautiful."

"To 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," the new father continued.

"Grateful to know her, proud to call her mine, and thankful for the life we will have together."

New mother Gigi has yet to share her own post after giving birth and previously the 25-year-old model revealed she didn’t want to "share" too much of her pregnancy on social media.

She said: "Obviously, I think a lot of people are confused why I'm not sharing more, but like, I'm pregnant through a pandemic. My pregnancy is not the most important thing going on in the world. That's a reason that I felt that it's not really something that I need to share, apart from with my family and friends.

"Obviously a lot of people have lost lives due to coronavirus that was in the beginning of quarantine and is still happening. And then we moved obviously into the reemergence of the Black Lives Matter movement, and I thought that our presence on social media should be used for that."

Gigi confirmed her pregnancy in April.

She said at the time: "Obviously, we wished we could have announced it on our own terms but we're very excited and happy and grateful for everyone's well wishes and support. Especially during this time, it's a nice silver lining to be able to be home and be together and really experience it day by day."
