Kristen Stewart arrived at LAX yesterday to catch a flight out of town. Also at the airport were her On the Road costars, and real-life couple, Garrett Hedlund and Kirsten Dunst. The gang are bound for France, where their Walter Salles-directed movie will debut tomorrow — make sure to check out all the celebrities at Cannes so far during the festival! Kristen has been around the world in recent weeks talking up her other new film, Snow White and the Huntsman, and was last in Mexico City to do a round of interviews alongside costar Sam Claflin. France may bring Kristen a little relaxing. Her boyfriend Robert Pattinson will also be on the Croisette with his movie Cosmopolis, so hopefully they're able to fit in a date night amid the premieres, parties, and press.
