Kristen Stewart arrived in skinny jeans and a knotted t-shirt for a vinyasa flow yoga class in LA today and later stepped out wearing a gray Make Believe tank and Under Armor leggings. The past two weeks have been relatively quiet for the actress since returning from a brief trip to London where Kristen hung out with On the Road costars Garrett Hedlund and Tom Sturridge. Kristen and the guys have a few more months before their American classic comes to life on the big screen, and before then she'll have her hands full promoting another highly anticipated project, Breaking Dawn Part I. We've already seen the first Breaking Dawn teaser — full of romance, a honeymoon surprise, and plenty of action — but we'll have to wait until November for Bella and Edward's big walk down the aisle. Until then the Twilight cast is working on other projects, Robert Pattinson's focusing on Cosmopolis, Taylor Lautner's prepping for the release of Abduction, and Kristen's getting into shape for her starring role in Snow White and the Huntsman.
