They came to the US to tour in May,him and Perrie were dating around that time,have been since Feb 2012. They came to the US in February. So between then and May-ish,when he was dating Perrie,he cheated/was going to cheat on her with this girl. He would've done it anyway like what he did to all of his previous girlfriends. If you think he never cheated on poor Perrie or never has cheated in his whole life,you're either blind and/or stuck so far in his ass. SO MUCH EVIDENCE in front of you all.
