British actress Sienna Miller is rumoured to be plotting a move to Los Angeles after making friends with Hollywood stars Josh Hartnett and Lindsay Lohan. The 25-year-old has wowed the US with her role as tragic Andy Warhol muse Edie Sedgwick in new movie FACTORY GIRL, and she wants to take advantage of her new popularity by moving to Hollywood. A source tells British newspaper The Mail on Sunday, "Sienna is looking for a flat on Sunset Boulevard in Hollywood as she doesn't want to come back to London. She's been accepted into the A-list clique over there by hanging out with Josh Hartnett and Lindsay Lohan. "The relationship with Jude Law is well and truly over - Sienna is tired of the London celebrity scene."
