The News Of The World  reports today that X Factor judges Simon Cowell and Cheryl Cole have reportedly quit the show in order to work on the American version..

The newspaper suggests that the move could well see an entirely new panel in the show’s biggest ever shake up – with even Louis and Dannii getting the chop!

“Losing Simon and Cheryl is a nightmare. We may be looking at an entirely new panel,” an insider told the newspaper.

They added: “There will be a massive shake-up. Simon is a huge, huge loss. He gives the judging panel such authority and there are big fears that millions will switch off without him.

“And two million extra viewers tuned in when Cheryl joined the panel. To lose her as well is a nightmare.”

Last year polls carried out saw Cheryl and Simon voted as the most popular X Factor judges, while poor Louis lingered in last place.

The source continued: “Dannii looks the most likely to survive. Louis’s position is in danger – but no one has been booted off yet.”
