Robert Pattinson put on his shades as he headed out of Comic-Con in San Diego this afternoon following a panel with Kristen Stewart and Taylor Lautner. His Twilight costar Ashley Greene also finished up her duties and was spotted leaving in a fun patterned dress. She arrived this morning with Nikki Reed, and the duo stopped to sign autographs and take pictures with fans before their press conference. Rob sat down with Kristen Stewart and Taylor Lautner to discuss their upcoming Breaking Dawn Part I, and they chatted about the end of the series and their favorite scenes. Robert Pattinson even shared his fear about being shirtless on camera! One lucky Twilight fan was in for an extra treat today since she got to meet Taylor in our latest I'm a Huge Fan contest. There's more coming from the sunny convention spot so be sure to check out Buzz for all the Comic-Con news.
