Nicole Kidman chose a black-and-white checkered dress for her latest Cannes Film Festival look. She stepped out this morning for a photocall with Hemingway & Gellhorn costar Clive Owen after also promoting The Paperboy. Nicole, Zac Efron, and Matthew McConaughey made multiple stops for their project, including the red-carpet premiere and an appearance on Le Grand Journal. Nicole will be back in the spotlight later today when Hemingway & Gellhorn screens at the Grand Palais. Matthew will also return to the festival's famous carpet for Mud, which also stars Reese Witherspoon. Reese arrived in the South of France with her husband, Jim Toth, just yesterday and we can't wait to see the glamorous looks she chooses for her many events. Nicole, Reese, Zac, and Matthew may all be friendly at the festival, but they're in direct competition for the top spot in the PopSugar 100.
