The X-Factor is back and Martin got a sneaky preview

It's back! And so is Sharon... yes, The X-Factor will return to our screens this weekend and Newsround's Martin got to go behind the scenes.

It's 10 years since the first show, and to celebrate the producers asked Sharon Osbourne to join the panel of judges once again.

It has been six years since Sharon sat up there and gave the contestants feedback.

The new series will also have some twists in the format, which include double auditions.
