well i don't know him so i'm not completely sure but why would he have sex with her, she is ugly and stupid and he has a lovely girlfriend..it would be really silly if he did it. and i rather believe him than her, she was in wc 2006 hotshots, a dutch programm, it's obvious she wants attention.
i think robin van persie is a good man, cheating on bouchra like that would show he hasn't got any respect for his wife and bouchra supported him when he was arrested for rap en she's pregnant of him that says enough i think.
