The X Factor judges have reportedly filmed a Game of Thrones themed advert.
Simon Cowell, Cheryl, Mel B and Louis Walsh were joined by hundreds of extras at Pinewood Studios shooting the reported £1 million trailer, the most expensive in the show's history.
The short film - which took a week to film - sees the quartet lead singing warrior armies into war as they prepare to do battle to take the X Factor throne, echoing the fantasy drama which sees warring families competing to take control of the seven kingdoms
The advert, which was reportedly helmed by One Direction music video director Ben Winston, also made extensive use of green screen and CGI technology.
Mel B shouts: "Things are about to get loud."
Cheryl winks and orders her 'army' to charge, while Simon warns: "It's time to get down to business."
The new advert will air for the first time on ITV tonight.
