Sharon Osbourne is bemused by the choice of contestants on upcoming British reality TV show CELEBRITY X FACTOR - because she has no idea who any of them are. The wife of Ozzy Osbourne is a judge on the show, on which celebrities will pit their vocal skills against one another. But her time away from the UK living in Los Angeles means she doesn't know most of the show's stars, who include magician Paul Daniels, his ex-wife Debbie McGee and soap star Lucy Benjamin. Osbourne says, "I don't know who the bloody hell they all are. I'm going to be the same as normal, be very honest. "I've never heard of any of them apart from (BBC radio presenter) Chris Moyles, because Ozzy went on his show. I didn't even know he could sing. "Unless they've made a record or been in a movie, I wouldn't know them. I've been back in LA for a while."
