Gigi Hadid and Zayn Malik got back together at the end of last year, and the two have kept their relationship away from the eyes of fans for the most part. But on Friday, the day after her 25th birthday, Hadid celebrated by sharing a rare photo of her and Malik celebrating. Among a collage of photos, Hadid shared a photo of herself sharing a cozy hug with her boyfriend, who wore a quilted coat fit for quarantine.
