Kristen Stewart arrived at LAX today to catch a flight out of town. She sported her signature ensemble of jeans and a t-shirt and swapped out the broken sunglasses she's been wearing recently with a pair of shades that were in one piece. It's not confirmed where Kristen is headed, but she may be treating herself to a vacation since she wrapped filming on her latest film Camp X-Ray last week. As Kristen finishes one project, her ex Robert Pattinson has been spotted around town working on another. Robert was all smiles with costars Julianne Moore and Mia Wasikowska while shooting David Cronenberg's Maps to the Stars over the weekend.
