The dumped lover of Hayden Christensen has blamed Sienna Miller for the breakdown of their relationship.

Lola Skye is furious to learn that the two stars have been secretly dating - and has accused Sienna of stealing her boyfriend.

"I've been very hurt and betrayed by both of them - especially Sienna," Lola told the News of the World. "She has a lot of problems. She has a messed-up temper and is so erratic. She's just not the sort of person I want to be around.

"I hope she realises that not everyone is responsible for her ex-fiancé's cheating and that she doesn't have to take it out on everyone else."

Lola, who lives in Hayden's home town of Toronto, visited the star in London from February 21 to 26 and stayed in his flat. She has now discovered that he was still seeing Sienna during this period when her back was turned.

"While I was in London, Hayden kept disappearing," she explained. "I had no reason to question where he was going. I can't believe that the minute I was gone, he met up with her."
