Kristen Stewart stepped out of her limo onto the red carpet at tonight's Glamour Women of the Year Awards in London wearing another sexy, strapless, minidress. The Twilight star spent the weekend on the West Coast cozying up to boyfriend and costar, Robert Pattinson, at the MTV Awards where the pair took home the award for best kiss before debuting the first Breaking Dawn trailer. Rob and Kristen stuck together backstage during the show, and later Robert and Kristen cozied up to one another at Jason Sudeikis's all-star afterparty. Rob returned to Canada where he's currently shooting Cosmopolis, while Kristen made her way to London for tonight's fashionable fete alongside her On the Road costar Garrett Hedlund. Once inside, she took the stage to help present Garrett with his honors.
