Sienna Miller and Kate Moss stunned guests at a wedding the two were attending when they started yelling and fighting.

Kate, who has been friends with Rhys Ifans for years got pissed because ever since Sienna's been dating him, he hasn't made any time with her. She started yelling at her, saying that she stole her style and was trying to steal her life.

Sienna started yelling back, but Kate's bff Sadie Frost, the ex-wife of Sienna's ex Jude Law, stepped in and told them to squash it.

BITCH! How dare she break that up. OMG, bitches fighting at a wedding is the best thing EVER to watch. Scratch that. Two skinny bitches fighting at a wedding who eventually knock over the cake is the best thing EVER.
