Robert Pattinson and Kristen Stewart hit the red carpet on Wednesday night for a special Twilight fan event. Hundreds of supporters of the vampire series turned out to the screening in Battersea Park in London. Actor Taylor Lautner was also there. All three got a great reception and spent time happily signing autographs and posing for pictures. While chatting to reporters, Robert revealed what he goes for in a woman is a sense of humour, while Taylor says he likes a girl who can be themselves. The Twilight Saga: New Moon opens on November 20.
