"Someone stole, like, a million pounds' worth of Chopard jewellery from Cannes? I promise it wasn't me! It's crazy. That's really, really weird... I promise I'm innocent! I promise I had nothing to do with it! I went nowhere near the suites. I can have someone vouch for my whereabouts at the time of the robbery!" Harry Potter star Emma Watson, the star of new heist movie The Bling Ring, insists she had nothing to do with the Chopard jewellery theft at the Cannes Film Festival.
