Vanessa and Alysson Paradis took in Tuesday morning’s Chanel show in the chilly Grand Palais, where curiosity ran high about what might be under the giant white box in front of the audience. “I don’t know what’s in the box, but I think it’s something very cold,” Alysson remarked. Her sister Vanessa, just tapped to be the face of Chanel’s Coco Cocoon range of handbags, wasn’t in the mood for guessing games. “The show is starting,” she hissed. Alexa Chung was in the loop and knew there were icebergs inside. The British presenter said she would soon be filming another season of Channel 4’s fashion and music series, “Frock Me.” Bambou disclosed she’ll be jetting of to L.A. to discuss working on an album with Leonard Cohen. Chinese artist Yi Zhou has just completed the 3-D animated film “The Greatness,” with music composed by Ennio Morricone. “I’m going to have a mini retrospective at Sundance Film Festival,” she said, adding that an exhibition of her watercolors and sculptures will be on display during the World Expo in Shanghai this spring.
