Kristen Stewart got sexy in a short leopard-print dress in Paris today. She stepped out for the Louis Vuitton exhibit at the Musee des Arts Decoratifs, which showcases Marc Jacobs's 15 years of work at the fashion house. Kristen stopped by the designer's showroom on Monday after also popping up at Balenciaga's show last week. She wasn't the only famous face to show support for Marc ahead of the exhibit's public opening on Friday, since Robert Pattinson and Gwyneth Paltrow also came out for the event. Gwyneth arrived in France from London this morning, when she was spotted hopping on the Eurostar.
