Gigi Hadid Celebrates Zayn Malik's Birthday With a Sweet Message: "Team No Sleep!"

We don't need to tell you that Gigi Hadid and Zayn Malik make two of the cutest parents — just head to their Instagram accounts where they often share glimpses of their new life together. So far, they've celebrated the arrival of their new baby girl with adorable pregnancy photos, nailed the family Halloween costume, and also shared cute PDA-filled messages with each other, including Gigi's recent birthday message to Zayn.

On Jan. 12, Zayn celebrated his 28th birthday, and Gigi wrote the sweetest happy birthday message to celebrate. "Team No Sleep ! Happiest birthday to our Zaddy baba," she wrote on Instagram. "So special. Love you long time, thank you for makin me a mamma to the best girl ever ☺️ Wish you the best every single day." Along with the caption, Gigi posted two photos, one of her and Zayn linking arms (side note: where can we buy a pair of Gigi's incredible unicorn slippers?), showing a rare image of the two as parents, as well as an illustration of Zayn and their little girl.

Since her birth in September 2020, they've kept the privacy of their little one under wraps, not revealing her face or her name. Although, some fans have coined the adorable "Baby Zigi" to refer to the baby.
