10 Celebs Who Are Lousy in Bed

Just because someone is rich and famous does not, apparently, guarantee he or she is also good in the sack. The Frisky lists 10 celebrities who've gotten less than fantastic reviews from their former partners:

• Eminem: "He's not very well endowed," Kim Mathers once said. "If you're going to have sex with Marshall, make sure you have a little blue pill, because otherwise it does not work."
• Maria Sharapova: Adam Levine denies it, but he once reportedly said he was "disappointed" because he thought she would "be the loud screaming type."

• Paris Hilton: Nick Carter once called her "a drunken prude who as far as I can see did not really like sex. She relied on drugs and drink to give her confidence in the bedroom and was more often than not too wasted to even perform. I lost count of the nights I had to pick her off the floor and drag her to bed passed out."
• Brody Jenner: Kristin Cavallari once called sex with him "very ... vanilla."
• Russell Brand: "A disappointment," declared Georgina Baillie.
