Kate Moss is a naughty minx. She and pal Stella McCartney hit the La Clique circus-themed show at the Hippodrome in Leicester Square this week and things got a little out of control. My mole says: “Kate was completely out of it and kept lifting her dress.” And it didn’t stop there. In one scene a performer plays a kazoo using her intimate parts – and Kate fancied a toot. “She ran on stage laughing hysterically,” giggles my source, although in the end Kate didn’t actually have a go. Britain truly does have talent!
