Gigi Hadid commemorated the birth of her baby girl on Wednesday (Sept. 23) with a sweet post on social media.
"Our girl joined us earth-side this weekend and she’s already changed our world. So in love," she captioned the black-and-white photo of the baby grasping longtime love Zayn's thumb with her tiny hand.
The supermodel's sweet announcement came just shortly after the former One Direction-er confirmed the news with a similar post of his own, writing, "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. Grateful to know her, proud to call her mine, and thankful for the life we will have together x."
