Former One Direction member Zayn Malik, 23, and his supermodel girlfriend Gigi Hadid are adorable together. The British singer even spent time with his girlfriend's family on her 21st birthday, but according to latest reports, he has called it quits on his relationship.

As tragic as it sounds, sources said the "Pillowtalk" singer broke things off so that he could keep his "options open." This news comes weeks after the couple appeared on the Mat Gala 2016's red carpet and even cleared their schedules to spend quality time on Hadid's birthday.

"Gigi was shocked because she thought they were a perfect couple. She is absolutely heartbroken and has been feeling really sad ever since," Hollywood Life (via Life & Style Magazine) quoted a source as saying.

Until now, neither Hadid nor Malik has responded to the report. However, the Victoria's Secret supermodel's latest Instagram post indirectly rubbishes rumours of their alleged break up.

On Saturday, May 21, Hadid uploaded a picture of her and Malik and captioned it "missing you" with a heart emoji. According to another Hollywood Life report, the two haven't seen each other in three weeks, but perhaps it is work that's keeping them apart.

Rumours of Hadid and Malik's relationship began after the two were spotted at American Music Awards in late 2015. The singer, who had just called off his engagement with Little Mix member Perrie Edwards, started dating the model, who had broken up with Nick Jonas during the same time. Since then, they have been spotted together and even appeared on the cover of Vogue's April 26 issue.
