X Factor 2015 trailer revealed - and Cheryl is a robot

The new series of X Factor is almost upon us and here's a first look at the new line-up.

Hosts Caroline Flack and Olly Murs don white coats to go behind the scenes of the X Factor laboratory to find out the secret formula of this year's show.

In the mad scientist themed trailer new judge Nick Grimshaw gets microchipped.

But it appears it's last year's as all he can keep saying is Louis' catchphrase: "You look like a popstar, you sound like a popstar."

Another new face is former The Voice judge Rita Ora who seems to have a little trouble concentrating in her contestant feedback training - instead looking in the mirror at herself.

Next we see Geordie judge Cheryl as we've never seen her before - as a clone of Chez-Bots programmed for every possible emotion.

And Simon appears to have his shows mixed up when he predicts next year's winners "who are going to be bigger than One Direction" as these dogs.

And have we seen this chap at the end somewhere before?
