Fans began to speculate that the couple may have rekindled their romance, thanks to a few social media posts. The couple split just over a year ago.
Earlier this month, Hadid shared an Instagram story with Malik's mother Trisha tagged in it, writing, "Sunday in the kitchen about to marinate the chicken for one of my favourites!!! @mammamalik's Chicken Curry Pasta Salad."
Malik's mother reposted the story, and later reposted a video from a fan account where Hadid was asked "What’s your favourite restaurant in the world?" and she responded, "My boyfriend’s mum’s house."
This year, Hadid dated Bachelor alum Tyler Cameron before splitting in November.
Following her split from Cameron, she and her Zayn apparently got to talking again. "They went through a phase where they took time apart and weren't communicating at all, but they have been in touch recently," a source told E! News in November. "She is supportive of him. They chat here and there, but it's been casual."
While it's entirely possible they could be back together again, it's also reasonable to believe that after two years together, Hadid has remained close to Malik and his family.
