And because we all know how these threads are supposed to go...Resident Evil: Apocalypse beauty Sienna Guillory has launched a scathing attack on fellow Brit Kate Beckinsale for becoming one of the "bitchy Hollywood" set and allegedly having breast implants. The London-born actress says she is horrified by Beckinsale's transition from English rose to Tinseltown movie star and believes the rumors the Van Helsing star has gone under the knife. Guillory says, "In Hollywood, women hate each other. Everyone is so bitchy 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 be cool. Now I've heard she's got a clause in her contract saying that she can't be filmed bending over at more than a 45-degree angle because her boob implants slide up onto her collar bone." Beckinsale's agent Jane Brand responds, "I do her contracts and this is absolutely untrue. She has no clause in her contracts and this is absolutely untrue. She has no such clause in her contracts and she has categorically not had breast implants."
