Dannii and Cheryl can breathe a sigh of relief as it seems former winner Leona Lewis has no plans to put herself forward for The X Factor panel.

The singer told Contactmusic that she wouldn't be able to turn down any of the acts who audition for the talent show.

She said: "It would be fun. But I don't know if I'd be a good judge because I'd just say yes and let everyone through. I wouldn't be able to turn anyone away."

Leona, who won the 2006 series, is set to meet this year's contestants when she performs her new single on the show.

She added: "I can't wait to meet everyone, but I'm mostly looking forward to seeing the girls.

"They are aspiring towards the same things as me when I was on the show and are going through a similar experience."

We wonder if she'll still think so highly of them if she's jostling with them this time next year for the number one spot?
