Baby Zigi has finally arrived! Gigi Hadid and Zayn welcome their first baby girl together.

The model's father Mohamed Hadid posted a handwritten letter to his granddaughter on Instagram on Wednesday (September 16). "Hello little grandson, it's me, my heart can be happy. I wish you the sun and the moon, I wish you a happy time," the poem read. "Know that Grandpa is always near, I will do anything, I will do anything for you, my dear. When I heard you were on the way, I smiled and wiped away a tear. I cried because I knew; you. Mohammed Hadid.

Zayn confirmed the gospel. The former One Direction singer shared a post on social media. "Our baby girl is here, healthy and beautiful," he wrote.

"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, & thankful for the life we will have together."
