Keira Knightley has some strong words for misbehaving young starlets in Hollywood. The Pirates of the Caribbean star didn't hold back at the Venice Film Festival — where she was promoting her next movie, Atonement — when speaking about the likes of Lindsay Lohan, Paris Hilton and Britney Spears. "I'm not going to get blind drunk and then stumble out and fall over and puke up in front of people. I'm not saying I don't do that in private, but I try not to," she said. "The whole celebrity thing is not magic. They're real people proving they're s**ttier than everybody else because they don't even wear knickers." Ouch!
