Robert Pattinson headed to the circus today, kicking off filming of his new project Water for Elephants. This morning he scoped out the set in Ventura, and now he's a little bit dirty and oh so sexy in his new wardrobe. His heaviest costar is a world record holder, and perhaps Rob is in the running for hottest onscreen veterinarian? We love seeing him playful with Kristen and Taylor, but we're not complaining about how he looks for this movie! One place he is looking toward a title is the PopSugar 100 — he is currently making a run for it in the finals with a strong early lead over Sandra Bullock.
