Pop superstars Beyonce and Madonna are rumoured to have signed up for this week’s X Factor final.

We have already revealed that Paul McCartney, Michael Buble, Robbie Williams and George Michael will be performing with the X Factor finalists next week, now we hear that these two superstars may be giving solo performances.

If this rumour is true, it will be a bit of a déjà vu, as Beyonce also performed on last year’s final. She sang a duet with Alexandra Burke, check out the video below. Madonna has never appeared on the show before.
