The X Factor 2015: Cheryl, Rita Ora and Grimmy chat to Leah

The X Factor returns to our TV screens this Saturday with the hope of finding the world's next big music superstar.

The new series has two new presenters and two brand new judges.

Pop star Rita Ora and BBC Radio 1 presenter Nick Grimshaw are both joining the judging panel for the first time.

Leah caught up with them both and Cheryl Fernandez-Versini to find out how they've settled in to their new job, and what it takes to find the next star act.
