Kristen Stewart tied up her t-shirt and showed off her navel as she arrived at LAX to catch a flight to NYC on Sunday. Once in the Big Apple, Kristen slipped into a sweatshirt and joined up with some friends. Kristen is in New York to attend Monday's Met Gala before her Snow White and the Huntsman duties take her to London for the junket and premiere next weekend. Kristen's Snow White promotional duties also brought her to The Tonight Show With Jay Leno and Jimmy Kimmel Live this weekend. Kristen revealed her latest injury while chatting with Jay, and we'll get to see her interview with Jimmy when it airs tomorrow night.
