Paris Hilton previewed her new single, a cover of “Do Ya Think I’m Sexy,” at Tao in Las Vegas at a party following Madonna’s Confessions concert at the MGM Grand. There’s video from TMZ. If we hadn’t been told beforehand what song she was singing, we’d never have guessed. Backup sounds a bit like “Fly Robin Fly.” She’s got balls, though, to strut awkwardly around the stage in that graceless way she has after everyone had just seen Madonna. Still, Madonna was no paragon at her show earlier, scolding a member of the audience for not dancing and ordering the air conditioning to be turned off. We wonder: Is Madonna paving the way for Paris?
