The talent show judge has called for her boss to mix up the show's categories, in order to make the live stages of the competition more exciting.
Under Chez’s plan, each judge would mentor an act from each of the Boys, Girls, Over 25s and Groups, rather than looking after each group of contestants exclusively.
She told Radio 1’s Newsbeat: "I think it's far more exciting, not just for us as judges but also for the viewers at home. You're never going to have a runaway category, because they're always like, 'Well, the girls are obviously the best.'
"They might be like, 'Ooh, Rita's got the best boy, but Simon's got the best girl, and Nick's got the best group, but Cheryl's got the best over'."
The 2015 'X Factor' panel
While Simon has already unveiled the biggest changes to the series, with Dermot O’Leary, Mel B and Louis Walsh all axed and replaced with Caroline Flack, Olly Murs, Rita Ora and Nick Grimshaw, there are still reportedly more format changes afoot.
It has been claimed that the Judges Houses stage will be aired live this year, as the judges pick their top contestants to take through to the finals.
The ‘X Factor’ is set to return to ITV in the autumn.
