Kristen Stewart threw a glance over her shoulder as she made her way out of town at LAX Monday. She didn't stick around for the Fourth of July festivities in California, though she spent much of the weekend in the area. Kristen Stewart was spotted horseback riding in Palm Springs on Friday, which was presumably part of her training to start filming Snow White and the Huntsman soon. Kristen has also been working out a lot recently, with a few trips to her local yoga studio last week. Kristen will start shooting her fairy tale soon, and she only has a few months before the promotional road for Breaking Dawn ahead of its November release.
