Actress Julia Stiles has hit out at the tabloid media for rewarding the bad behaviour of stars such as Britney Spears, Lindsay Lohan and Paris Hilton. The Bourne Supremacy star claims extensive press coverage of the antics of Hollywood's party-loving elite only encourages young celebrities to misbehave. She says, "I think a lot of it has to do with being very young and having a lot of opportunity and money. "As for the attention, I feel we reward bad behaviour. They get a lot of attention for misbehaving, and it reinforces the idea this is who they're supposed to be. It may also be about them being young, experimenting and partying. They just get more attention than the average kid who does that. "And they're surrounded by people who won't stop them, because they're making so much money for everybody."
