Emma Watson looks like a princess at 'Beauty and the Beast' film launch

The stars of Disney's upcoming "Beauty and the Beast" live-action remake celebrated the film's highly-anticipated launch on Thursday in London -- and they donned their most elegant looks.

Emma Watson, who plays Belle in the flick, looked especially gorgeous at the event in a stunning, light-blue off-the-shoulder gown complete with a massive train.
