Robert Pattinson teamed up with his Twilight buddies today for Comic-Con in San Diego. He posed with Kristen Stewart and Taylor Lautner before a press conference at the Hilton Bayfront Hotel to chat up Breaking Dawn: Part I. Robert showed off the interesting haircut he got for his most recent film, Cosmopolis — he still rocked the half-shaved, half-regular 'do! Kristen also went for a unique look by pairing her dark bra with a light tee. Some of their costars like Nikki Reed and Ashley Greene rose early this morning to meet fans outside before the interviews commenced. Buzz is in Southern California live tweeting from Comic-Con, sharing quips from Rob like that he hopes to see a film in the series called "breakfast time." Ashley and Nikki spoke before Rob, Kristen, and Taylor and revealed a couple Breaking Dawn teasers.
