Being a member of the jury at the Cannes Film Festival is a major honor in cinema, and when you also happen to be a beautiful actress, this role comes with a whole extra set of responsibilities. Not only do you have to go to every screening, you also have to walk down every red carpet, which means you have to change between red-carpet-appropriate gowns all day. Last year, this task fell to Diane Kruger, who performed admirably in a parade of Chanel, Calvin Klein, Jenny Packham, Christian Dior, and so forth. For Cannes 2013, the token clotheshorse juror will be Nicole Kidman, which means that Keith Urban gets to be this year's Joshua Jackson. How exciting! Get ready for lots of L'Wren Scott, the actor's latest designer of choice.
