A cheerful Robert Pattinson took a break from filming Water for Elephants in LA earlier today. He's back in formal wear for the latest shots after looking dirty and quite dashing with his four-legged costars. Rob's not the only Eclipse star working this week — Taylor Lautner started shooting Abduction in Pittsburgh and Ashley Greene presented at last night's ESPYs in LA. Kristen Stewart, on the other hand, left town after taking in a few shows. It won't be long until production starts on Breaking Dawn this Fall, and from what screenwriter Melissa Rosenberg shared with us it sounds like Rob is in for an exciting ride.
