Perrie revealed: "It's more understanding because you get it and it's more exciting when you see each other.

"But when you don't see each other, you're so focused in the studio, our mindset is on what we're doing, so it's important to be like that."

Despite being a little bit jel, we're very happy for Zayn and Perrie. They do make an impossibly cute couple after all.
