Rylan Clark-Neal and Matt Edmondson bring The Xtra Factor LIVE to ITV2 but how will it work?
Well, even they don't know.
Chatting to us at the red carpet launch of The X Factor in the week, Rylan and Matt confessed they had no idea how the new look spin-off would go.
Matt told us: "It's live on Saturday, ITV2 9:30PM, people ask 'How Xtra Factor's going?' and we don't know!"
Rylan meanwhile poked fun at The X Factor's constantly changing judges and hosts: "We've very much knowledgeable that this is potentially a one series thing so we're going to go out with a bang.
"We're aiming together sacked before the end of the series."
Airing straight after the main show, Matt and Rylan will be joined live in the Xtra Factor studio by contestants who have appeared on the main show, getting the lowdown on their audition and getting to know more about them.
There will also be live music and a panel of celebrity guests on hand to give their uncensored thoughts and reactions to the night's auditions.
The Xtra Factor Live’s digital reporter, Capital Radio DJ Roman Kemp, will also be on hand to bring viewers all the social media news and reaction to that week’s auditions.
A brand new segment titled 'Louis' Gap Year' will give viewers an exclusive look at what Louis Walsh got up to during his time off last year as we follow him and Sinitta on a trip around the world.
As Matt and Rylan join forces they will also be bringing viewers the usual mix of unseen auditions, interaction with fans on social media, backstage gossip and access to the all-important X Factor judges.
The Xtra Factor begins tonight on ITV2 at 9:30PM and continues straight after the main show each Saturday and Sunday.
