Zayn 1D accused of cheating.
According to this he's been naughty.
Not blaming the alleged other girl but I call shenanigans on her not knowing about his GF. The way I see it, if you know who to call about your 1 nightstand with a celeb, chances are you know enough about that persons personal life to make that call.
I feel sorry for her, the 1D fans are going to slaughter her.
