Kristen Stewart exited her gym in LA today with a bright smile and her t-shirt rolled up to show off her arm muscles. Kristen's been attending yoga classes in preparation for her physically demanding role in Snow White and the Huntsman, which begins shooting later this year. Her boyfriend, Robert Pattinson, had a late one yesterday on the set of his own project, Cosmopolis, filming scenes with a gun and once again getting a pie thrown in his face. Rob and Kristen will reunite professionally in November to promote Breaking Dawn Part I, but their costar Taylor Lautner will be headlining his own high-paced action flick Abduction before then. We're giving one lucky fan the opportunity to meet and interview Taylor at Comic-Con, so make sure to take our quiz and enter to win the chance of a lifetime!
