A very first look at The X Factor: The Band has been revealed ahead of Monday's launch.
The new spin-off will see singers audition to form part of a girl group and boy band.
Hosted by Dermot O'Leary, Nicole Scherzinger and Simon Cowell will feature as judges and mentors of the bands.
A new trailer features the pair sitting behind a desk at Simon's record label as auditions begin.
It comes as sources claim the competition will feature "the toughest auditions in years".
"Simon means business and wants no one wasting his time," a source shared with the Daily Mail newspaper. "He's looking for the band of 2020 and for a group to follow in the footsteps of One Direction and Little Mix.
"Auditions have been taking place at Simon's record label, with auditions being across Syco in front of a host of industry professionals."
They added: "This isn't a TV audition, it's the biggest record label meeting the prospective artists could ever hope for.
"Simon and Nicole aren't putting just anybody through. These are undoubtedly the toughest auditions in years."
Alongside Nicole and Simon, a number of singers, producers and other industry experts will help out during the auditions.
They will include former X Factor winner Leona Lewis, singer Ella Eyre & producer Naughty Boy.
The X Factor: The Band will air over four episodes starting on Monday, December 9 at 8:30PM on ITV.
The series will then continue on Wednesday, December 11 and Friday, December 13 before a live final on Sunday, December 15 at 8PM.
