The couple has called it quits after two years of dating.
The former couple celebrated their second anniversary back in November, but hadn't been spotted together since late January 2018.
The former One Direction singer was the first to confirm the news, posting a statement to his Twitter page:
"Gigi and I had an incredibly meaningful, loving and fun relationship and I have a huge amount of respect and adoration for Gigi as a woman and a friend. She has such an incredible soul. I'm grateful to all of our fans for respecting this difficult decision and our privacy at this time, we wish this news could have come from us first. We love you all."
Hadid followed it up shortly after with a statement of her own:
"Breakup statements always seem impersonal because there is really no way to put into words what two people experience together over a few years .. not only in the relationship, but in life in f=general. I'm forever grateful for the love, time, and life lessons that Z and I shared. I want nothing but the best for him and will continue to support him as a friend that I have immense respect and love for. As for the future, whatever's meant to be will always be. xG"
Malik recently told Billboard that the two "pretty much live together."
"It's actually not that hard for us [to line up schedules]," he said. "It helps that she's really organized. Thank God because I'm really not, so she helps organize my schedule around seeing her."
Malik also mentioned that Hadid is one of the only people who gets to hear his music while it's a work in progress. "She's in the studio quite a lot," he said. "She likes to cook for me and stuff. When I'm here late, she'll come down and bring me food. She's cool."
Zayn made headlines earlier this year for his latest tattoo, a pair of eyes many fans speculated were Gigi's. That might be a little awkward for his next girlfriend.
