The X Factor 2015: Cheryl wants to mix up categories

Cheryl Fernandez-Versini says she wants to mix up the contestant categories on The X Factor this year.

The singer is pushing for the format to be changed so that each judge mentors a boy, a girl, a group and an over.

Head judge Simon Cowell has already brought in big changes for 2015, with two new judges - Rita Ora and Radio 1's Nick Grimshaw.

Cheryl said: "I think it's far more exciting, not just for us as judges but also for the viewers at home."

Hiring Radio 1's Grimmy is one of several changes Simon's made to the show this year
