Emma Watson changed into flip-flops to stroll around the LA set of The Bling Ring yesterday. The British star has been hanging out on the West Coast for the last few weeks working on the picture, which is directed by Sofia Coppola. Emma stars in the film alongside Leslie Mann and Kirsten Dunst, as well as a roster of actors with smaller parts, like her fellow Brit Gavin Rossdale. Emma managed to fit the project into her busy school schedule — she's been at Oxford, on leave from Brown, for the last year. She also shot a movie, The Perks of Being a Wallflower, last Summer during a break from college. That film finally hits theaters later this year on Sept. 21.
