Kristen Stewart wore a sexy sequined Roberto Cavalli gown for the premiere of Breaking Dawn Part 1 in London today. After ditching her heels, Kristen changed into sneakers while still on the carpet! She posed with leading men Robert Pattinson and Taylor Lautner just days after the trio stepped out together for the film's world debut in LA. Rob and Kristen shared sweet moments at the West Coast event, which brought out thousands of fans hoping to catch a glimpse of the Twilight stars. Rob stopped to sign autographs for a few lucky ladies on his way to the afterparty, where Taylor, Kristen, Peter Facinelli, Kellan Lutz, and more let loose to celebrate the film.

The Breaking Dawn Part 1 cast is in full press mode ahead of the movie's release in just two days.
