Harry Potter star Emma Watson trashes out in hair extensions and ”stolen” Herve Leger for her based-on-a-true-story new role: one member of a gaggle of celebrity-crazed, brand-obsessed, reality-TV-bred L.A. teenagers busted in 2009 for lifting nearly $3 million worth of goods from the homes of starlets such as Lindsay Lohan and Rachel Bilson. ”They were kids who just assumed they were going to be famous and have a fashion line because they thought they were fabulous,” says director Sofia Coppola, who looked to 1970s teenage-rebellion films like Over the Edge for inspiration. ”I don’t want to say they’re gross, but they are products of our reality TV culture.” Naturally, Paris Hilton makes a cameo in the film as herself.
