The Twilight cast united at Comic-Con in San Diego today to chat up the final installment of their series, Breaking Dawn Part 2, which hits theaters in November. Kristen Stewart chose a neon skirt from BCBG Max Azria and Barbara Bui sneakers for the event while Robert Pattinson showed off his longer hair. The duo posed on the red carpet before heading into a large panel with their costars. Kellan Lutz, Ashley Greene, Peter Facinelli, and Nikki Reed were on hand after kicking off the fun at a special party in their honor yesterday. It's a bittersweet appearance for the actors, since it's their last time at Comic-Con on behalf of Twilight, but Rob joked that he might just return next year dressed as Edward Cullen. There were some more serious moments during the press day, with Kristen chatting about the possibility of sex scenes and her vampire transformation as Bella.
