The impossibly good-looking pair are rumoured to have ended their relationship after seven months together, although neither have confirmed that's true.
Gigi did, however, share a Snapchat of a card featuring the words: "I know it's obvious but I love you." Is that her way of saying the speculation isn't true?
Many US outlets published unconfirmed reports Gigi and Zayn had split but a source told People it likely wasn't permanent, saying it's more like a break.
Another insider told E! News: "Zayn and Gigi did break up, but they can likely get back together tomorrow. It's all very unclear what's going on between them now."
Gigi, 21, and Zayn, 23, were first linked last year and she then appeared in his debut music video for 'Pillow Talk', released in January. He confirmed their relationship in February, but both have been relatively private about the romance.
They starred together in a Vogue photoshoot and have occasionally shared images to social media. They made their red carpet debut at the Met Gala in May, and just two weeks ago Gigi tweeted about how much she was missing her musician beau.
