So much for flying under the radar. Sacha Baron Cohen, who had so much success playing bumbling Kazakhstani reporter Borat, is finding it's much harder to go incognito as his flamboyant fashionisto alter ego, Bruno. Yesterday, Sacha, as Bruno, tried to crash the Versace runway show by latching onto the Marie Claire group, but no one was buying it. "Cohen arrived at the door with editor Joanna Coles and her team, and he kept telling security he was with the magazine," an insider tells the New York Post's Page Six column. "Coles denied he was part of their group, and he was not allowed entry." The movie based on Bruno is scheduled for release next year.
