Zayn's friend who brought her back to the house has posted her number on twitter saying 'people shouldn't tell lies.'
She obviously knew who he was, she either did sleep with him and saw it as a money making/fame opportunity, or she's taken advantage of him being asleep and taken the photo. Either way it's so blatantly calculated on her part, who takes a photo of somebody's back when they're sleeping?
Hasn't there been stuff in the past about Zayn cheating? I remember something about a telephone call where he was telling girls to hurry up and come to his hotel room.
