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 co-stars like Nikki Reed and Ashley Greene rose early in the morning to meet fans outside before the interviews commenced. Ashley and Nikki spoke before Rob, Kristen and Taylor and revealed a couple Breaking Dawn teasers.
