Kate Beckinsale has been accused of turning into a diva by fellow British actress Sienna Guillory - who claims the 'Pearl Harbor' star has a contract clause to disguise her alleged boob job.Sexy Sienna, who stars in new movie 'Resident Evil 2', has slammed the brunette beauty - who now lives in Los Angeles with director husband Len Wiseman - for letting Hollywood change her.She said: "In Hollywood, women hate each other. Everyone is so bitchy, because it's all about looking pretty and they don't want younger actresses coming in and taking their roles. "You only have to look at what it's done to Kate Beckinsale.

She used to be cool.

Now I've heard she's got a clause in her contract saying she can't be filmed bending over at more than a 45 degree angle because her boob implants slide up to her collar bone."However, Kate's agent, Jane Brand, vehemently denied Sienna's allegations, saying: "I do her contracts, and this is absolutely untrue.She has no such clause in her contracts and she has categorically not had breast implants."
