Hadid added that being in quarantine with her family had allowed her to feel every moment of her pregnancy. “It’s a nice silver lining to be able to be home and together and really experience it day by day,” she told Fallon.

Gigi’s father, Palestinian-Jordanian real estate developer Mohamed Hadid, shared a touching handwritten letter to his grandchild ahead of her birth. “Hello little grandchild, it is me, my heart as happy as can be. I wish for you the sun and moon, I wish for you a happy time,” the poem read. “Know that grandpa’s always here, I’ll do anything, anything for you, my dear. “When I heard you were on the way, I smiled and wiped a tear away. I cried the tear because I knew my heart would always belong to you.” Hadid, 25, and Malik, 27, have been in an on/off relationship since 2015. They broke up for a period in 2018, but it was confirmed they were back together in December 2019.
