Gigi Hadid has shared a new glimpse of her daughter with Zayn Malik as the parents marked their first Halloween as a family of three. The supermodel, 25, shared a family portrait of the trio to Instagram Stories on October 31, as they posed in their festive costumes. "My first Halloween," Hadid captioned the shot. The new mother, who has Palestinian heritage, was dressed as Samus Aran from Nintendo game <em>Metroid</em>, while British-Pakistani singer Malik took style cues from <em>Harry Potter'</em>s Draco Malfoy and sported a Slytherin uniform. Their daughter, who was born in September, wore a green jersey and a knitted green hat, with black woollen hair. A Hulk arm has been photoshopped over her fist, and a glimpse of her sandy hair can be spied underneath a superhero emoji covering her face. The couple had previously only shared images that showed their first child's hand, as they confirmed her birth on September 23. "Our girl joined us earth-side this weekend and she’s already changed our world. So in love," Hadid wrote on Instagram at the time. "Our baby girl is here, healthy and beautiful. 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, and thankful for the life we will have together x,” Malik, 27, posted on his own Instagram page. The supermodel and the musician are yet to announce the name of their daughter, but fans have nicknamed her Zigi. News of Hadid's pregnancy was first revealed in April, and the model later confirmed the news to US chat show host Jimmy Fallon, saying the couple were “extremely happy and excited”. The model and Malik 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.
