Perrie, maybe sleeping with groupies too? I don't know what zayn is like as a whole so I cant comment too much on his character, maybe he should stay single for a bit, and enjoy the things that come with the fame! He and Perrie are practically fresh from their teens, why would they want to set up house at 20.
Interestingly, it does give insight into the amount of "evidence" the tabs are willing to accept, I mean, let's be real, those pics can be anything.
Either way, I don't envy zayn, lol!
