“Happiest birthday to our Zaddy baba.”
The model celebrated Zayn’s first birthday as a father with a post on Instagram, referring to the couple as “Team No Sleep.”
“Happiest birthday to our Zaddy baba,” Gigi wrote. “…Thank you for makin me a mamma to the best girl ever.”
She also shared photos of his birthday party on her Instagram story, which seemed to consist of an entire arcade set up in their home.
The posts come four months after the couple announced they had welcomed their daughter following a relatively private pregnancy.
And while they have yet to reveal their baby’s name or face, Gigi has shared a select few photos with fans since giving birth.
