mischa_barton_05.jpgMischa Barton was reportedly livid that her supposed friend model Victoria Silvstedt wanted to hang out at the Cannes Film Festival.

According to the Mirror, the pair attended the exclusive De Grisogono party on Tuesday night and happily downed cocktails together for most of the evening before Mischa decided to go off on her own. Victoria then shouted after her: “Where the hell are you going now? Why do you keep walking away from me?”

With fellow guests including Naomi Campbell, Eva Mendes and Kid Rock looking on, Mischa replied: “We’re not even going in the same direction. We’re not going to the same place.”

A source added: “Mischa was fed up of Victoria’s whining and was telling her to move on. But Victoria completely lost it.”

“Just as Mischa was leaving she shouted, ‘There goes the b****! There goes the b****!’ It was highly embarrassing.”
