ITV has released a teaser trailer for the new series of The X Factor, which plays up the show's adversarial nature.

The series is due to return later this month for its 11th season, broadcast date to be confirmed.    

Returning judge Cheryl Fernandez-Versini has said that new judge Mel B has brought out the troublemaker in her. 

The Press Association quotes Fernandez-Versini as saying : "The troublemakers are always Simon [Cowell], and Melanie is trouble but in the best way possible. In fact, she brings out trouble in me, so maybe the two of us together are trouble." 

Cowell said: "This whole thing about girls falling out, that's not happening." 

He added: "Everyone we've put on the show this year, we've said specifically you've got to put the hours in to find some stars."
