The former One Direction star and model Gigi were first romantically linked in November (15), not long after Gigi split from Joe Jonas and only a few months after Zayn parted ways with his ex-fiancee, Perrie Edwards.

Neither confirmed the romance, but they regularly fuelled speculation by posting pictures of one another and holding hands while out and about. Gigi was even spotted with an image of Zayn as her cell phone's screen saver last month (Jan16).

The pair look more than comfortable in each other's company in the video for Zayn's debut single and a fan recently asked if it was "cool to have (his) girlfriend in the video," to which the singer told radio show Zach Sang & the Gang, "Uh, yeah. That was cool. it was something different. We enjoyed it. It was fun."

A co-host then followed up and asked, "No one easier to make out with than your own girlfriend, right," to which the singer responded, "Exactly".

Ironically, Gigi was also involved with her ex-boyfriend Joe's video for his band DNCE's Cake By the Ocean.

The pretty model made her directorial debut behind the camera for the promo, and Jonas admitted at the time she was a natural.

"It was her idea for the video and we were like, 'F**k it, you should do the video', and she just ran with it," he said.

"She had a megaphone. She was a bada**. Everybody really looked up to her to lead and she really came through and showed us that she could do it."

The zany promo features comedian the Fat Jew being pelted with desserts as he takes part in a cake fight.
