Supermodel Gigi Hadid and former One Direction band member Zayn Malik are two of the hottest celebrities walking the red carpet. So, it's no surprise that these two heartthrobs would couple up. Hadid and Malik first started dating in 2016 and have been on-again-off-again ever since. After being mostly off since early 2019, however, relationship rumors have started to circulate once again. Not only have the pair been spotted together in the new decade, but Hadid also recently posted a very revealing photo on Instagram that has fans and news outlets across the board insisting that Zigi--as the relationship has been dubbed--is officially back on.
