In very unlikely news we're hearing that Madonna is reportedly replacing Simon Cowell as a judge on 'American Idol.'

It's impossible to believe that her Madgesty would even consider it, though.

According to the British tabloids, Madge is said to be show boss Simon Fuller's first choice to replace the music mogul after Cowell announced he was leaving the panel to concentrate launching the "X Factor" stateside next year.

She may be his first choice but that does not mean it's happening anywhere except in his imagination.

A source said: 'Simon is going to leave a gaping hole. Not only is he an expert, he's also a big star in the States. Everyone agrees Madge would be great and they want her as a full-time judge. But if that fails they'd at least like her as a mentor.'

Fuller is said to be 'desperate' to hire the Vogue singer to join the current judges Ellen DeGeneres, Randy Jackson and Kara DioGuardi on America's most notorious judging panel.

Meanwhile 'American Idol's' season's winner will be announced tonight in a two-hour finale which is set to feature a performance from Christina Aguilera.
