Cowell and Cole 'quit X Factor'

Simon Cowell and Cheryl Cole have reportedly quit the UK 'X Factor'.

The pair - who are joined on the ITV1 show's judging panel by Louis Walsh and Dannii Minogue - have decided to leave their roles to concentrate on the launch of the US version of the talent competition, leaving 'X Factor' bosses terrified it will spell trouble for the new series, with auditions starting in just two weeks.
