Wasn't it oly last week when Sienna Miller was shouting that boys are bad and you could only rely on your girlfriends???? What she meant was HER boyfriends where bad and she was going to nick her girlfiends BOYS!!!
Pictures have emerged of Miller and her co-star Hayden Christensen kissing in the front seat of a car, unfortunately Christensen had a girlfriend at the time !!! Talk about two-faced!!
Lola Sky (Hayden's girlfriend) has told The News of the World
She knew exactly what Hayden and I meant to each other, I've been very hurt and betrayed by both of them, especially Sienna. She has a lot of problems. She has a messed-up temper and is very erratic. she's just not the sort of person I want to be around. 
She went on to say that she and Hyden had spoken and he had denied being romantically involved with her, but later he had broken down and said
that he was involved with her and that she had pushed him into it and that it was just a fling 
Oh that's alright then, Hayden, as long as it's just a fling and you got pushed into it, it's not your fault then. As much as I think Sienna is a cow for doing this when she knows exactly how much it would hurt Lola, you have to remember it takes two to have a fling - so maybe Lola is better off without Hyden!!
