Sharon Osbourne has been accused of being a prima donna by one of last year's finalists.

Chenai Zinyuku says that the judge came up with a long list of demands for producers before the 2005 live finals.

"She demanded the largest dressing room and told them how she wanted it decorated," Chenai told The People. "She was only in it for a few hours but she wanted new carpets in a certain colour and everything custom-made."

Chenai also warned this year's hopefuls not to expect lasting fame from the show: "I thought everyone would love me after X Factor but you just don't get taken seriously."
