Kristen Stewart arrived back at LAX last night following a whirlwind trip to Paris. She spent less than a week in France, but nonetheless managed to work with some of fashion's biggest names while there. Kristen donned a ball gown for a photo shoot lensed by Mario Testino that's apparently bound for Vanity Fair. Additionally, she spent a couple of hours chatting with Chanel's Karl Lagerfeld at a café. All the press is being done well ahead of her blockbuster Snow White and the Huntsman's release on June 2. There was time for some non-work fun, too. Kristen shopped at the childrens' boutique Bonpoint, and met up with friends at Café Germain. A sushi lunch was also on the initerary for Kristen at Hanawa, a restaurant Gwyneth Paltrow recently tweeted about loving.
