Los Angeles: After Taylor Swift and Calvin Harris, another star couple -- singer Zayn Malik and supermodel Gigi Hadid -- has reportedly called it quits.

While the reason behind their split remains unknown at the moment, a source has claimed that the couple has gone through some rough patches. "During her birthday they were fighting," an insider said, adding that they weren't doing well then, and have "broken up and got back together a few times". However, another source has claimed that there may be a reconciliation in the near future. "Zayn and Gigi did break up, but they can likely get back together tomorrow. It is all very unclear what is going on between them now. They been having some issues lately that involved communication and getting along," the insider said. "Gigi is really sad about this, though, and in a way would like to work it out. It is more about that constant contact with Zayn that she misses and they did get very close," added the source.
