Sharon Osbourne has claimed that Simon Cowell prefers "very skinny, very young" female judges on The X Factor.
The outspoken 61-year-old, who was a judge on the last series alongside Gary Barlow, Nicole Scherzinger and Louis Walsh, also said the TV mogul looks for someone he can boss about as she appeared on ITV's Loose Women.
Asked by panellist Jane Moore what Simon looks for in a judge, Sharon said: "You've got to be very skinny, very young..."
She continued: "He'll tell you what to say, he'll tell you what to do. You go, 'Oh I want that one.' He goes, 'No you don't.' Then you go, 'Oh, no I don't. No, no, no.' You've got to be able to be told what to do and that's why I can't do it because I'll end up giving him a..."
Simon will return to the X Factor judging panel in the coming series, alongside Cheryl Cole and Louis Walsh. A fourth judge has yet to be announced, with Mel B tipped for the seat. Previous female judges include Tulisa Contostavlos, Dannii Minogue and Kelly Rowland.
Sharon, who was previously a judge on the ITV singing show for four series from 2004 to 2007, said potential judges have to have experience of the music industry.
She said: "I think you've got to have a total understanding of the music industry today and you've got to have an understanding of marketing because it's not just about the best voice. You've got to tick all the other boxes - you've got to have likeability, you've got to have charisma, you've got to know how to work with an audience. You can have the best voice in the world but if you've got no likeability you're done."
And she confirmed she has no plans to return because she's focusing on her role on US chat show, The Talk.
"I can't come back. I mean, I love the show, it's become a part of British culture that show, everybody loves it and you can't help but get pulled into it. It's too much and I'd lose my job in America," she said.
"They let me out for one season and I don't want to do that to them again and also I've got a family," Sharon added.
