Cheryl is due to unveil new music this autumn, four years since she released her last album 'Only Human'.
It was claimed that TV programmes had been fighting to get Cheryl on their shows, but she'll "remain loyal" to The X Factor.
Cheryl was a judge on the show between 2008 and 2010 and then again between 2014 and 2015.
A source told The Sun newspaper previously: “She has decided to remain loyal to The X Factor rather than give the exclusive to its rival, BBC’s Strictly Come Dancing. And Cheryl will be pulling out all of the stops to make sure that this is one of her most talked-about performances to date.”
Cheryl's new single is rumoured to be called Love Made Me Do It and apparently alludes to her recent split from One Direction's Liam Payne.
Liam himself will also reportedly be making an appearance on The X Factor live shows to promote his own solo music.
"Cheryl is relaunching her music career on the show, and Liam will be trying to get a top hit after his last record, First Time, flopped," a source told the Daily Mirror newspaper. "It will be interesting to see how they both do when given the same platform.
"Both have written about the breakdown of their relationship in their new music, so they could end up singing about their break-ups on the same stage.”
More names rumoured to perform on The X Factor live shows include Kylie Minogue.
The X Factor live shows begin next Saturday, October 20 and Sunday, October 21.
The Saturday episode will run for a marathon two hours, ten minutes between 8:25PM and 10:35PM while Sunday's show will air for an hour between 8PM and 9PM.
