Gwyneth Paltrow  posed in a sexy black suit at a special event for the Louis Vuitton — Marc Jacobs: The Exhibition in Paris this evening. She traveled to France via Eurostar from London this morning, though she was a little more dressed down in a cozy sweater for the trip. Gwyneth's timing meant that she missed the Louis Vuitton runway show earlier today, which was attended by Dianna Agron  and Sarah Jessica Parker . SJP also stepped out for an early viewing of the exhibit, as did Kristen Stewart  and Robert Pattinson . Kristen and Rob shared a romantic dinner  date over the weekend, after Kristen attended the Balenciaga show solo on Friday.
