Diane Kruger attended the premiere of her movie Les adieux à la reine, or Farewell, My Queen, in Paris this evening with her costars Léa Seydoux and Virginie Ledoyen. Diane wore a lace, collared dress by one of her favorite designers, Derek Lam, for the occasion. The actress's latest film features her as Marie Antoinette and will open in select theaters stateside on March 21. Diane made the trip to France following a recent stay in LA, during which she attended the Vanity Fair Oscars afterparty solo and was spotted getting domestic the following week, running some dressed-down errands. The French premiere of her period film follows the Berlin Film Festival debut in early February. Farewell, My Queen will be Diane's first movie to hit American theaters since the thriller Unknown, which came out in February of last year and starred Diane opposite Liam Neeson and January Jones.
