Robert Pattinson: Swine Flu Scare?

Robert Pattinson suits up in Burberry Prorsum as he arrives for his interview with David Letterman at NYC’s Ed Sullivan Theater on Wednesday (November 18).

The 23-year-old actor’s co-star (and rumored girlfriend) Kristen Stewart also wore Burberry Prorsum over the weekend!

During the interview, Rob said he was into biting his fans. Letterman warned, “That’s not healthy, especially with the swine flu going around.” Rob replied, “And it depends on what you want to get out of it at the end. There’s variations of biting.”
