Naomi Campbell moves behind the camera for new modelling show "No, I've never done that," West says, adamantly. If you're associated with a particular product or commercial, you can get stuck with that, and people imagine you're not available for serious acting. Least said, soonest mended, then, about Prunella's turn as Dotty Turnbull in Tesco's "Every Little Helps" adverts in the mid-1990s. They reputedly made her £1 million. Miss Scales became so associated with Tesco that, during the last general election campaign, Gordon Brown invited her to tour a store in west London with him. She memorably observed of then prime minister: "He is absolutely brilliant and he is so good with people." Tracey's new foe Tracey Emin used to get it in the neck from Dinos Chapman, her fellow artist, for her "criminal" support of the Government. Now, she had better keep well clear of another fellow member of the chattering classes. "I'd love to meet a nice, reasonable, intelligent Conservative who's a lovely person, but where are they?" wails Zadie Smith, the author of White Teeth. They've disappeared. Happily, Emin and Chapman, one half of the achingly fashionable Chapman Brothers, did eventually make up.
