Zayn Malik and Gigi Hadid are hit by reports that their relationship in on the rocks. The two have apparently taking things slowly.

It was previously reported that the former One Direction singer broke-up with the model after her birthday. A source told Hollywood Life: "Things between Zayn & Gigi are not entirely over, they are just cooling off." 

"Zayn still has very strong feelings for Gigi," the insider added. "He has a lot of passion for her as she has been an inspiration to him since the day they met. However, they are not spending much time together lately and are not hanging out as much as they once were."

"Their schedules with work have both kept them busy and away from each other," the source continued. "They are not completely over yet, but instead are taking space from each other and not entirely on purpose, that's just how things are between them right now."

Meanwhile, in an interview with Billboard magazine, Malik talked about what he is looking for in a relationship. He said: "I need a challenge. Also, I like girls that are a bit chunky in certain areas — the nice areas. I like a fuller woman. I enjoy an intellectual conversation as well, where someone can construct a sentence beyond what hair and makeup they're wearing, and talk about something political or about the world. I like an opinion."
