Robert Pattinson was still rocking his asymmetrical haircut to accept the honor of Choice vampire at tonight's Teen Choice Awards in LA. Rachel Bilson and Joe Jonas had the honor of presenting the Twilight star with his latest neon surfboard. Rob took to the podium to thank fans and also share details about a new cancer-fighting campaign, aptly titled Cancer Bites, which kicks off nationwide Oct. 31. Rob was joined by his costars Taylor Lautner, Ashley Greene, and Nikki Reed in the audience, but one lovely lady noticeably absent from the show was Kristen Stewart, who is currently filming Snow White and the Huntsman overseas.
