In an extra X factor twist, judges will duet with their remaining contestants during this weekend's final.
Regrettably this means we'll be deprived of Louis and Kitty honking their way through 'The Edge of Glory', but we will get the opportunity to see Tulisa and Little Mix perform an Alicia Keys medley, Kelly and Amelia tear through 'River Deep, Mountain High' and Gary and Marcus undertake a Take That greatest hits set.
A 'source' 'close to the show' told The Mirror: “It’s going to be more pressured than ever. The acts will be singing in front of 10,000 people – and with their mentors. The judges will be nervous as well because the song could be the difference between winning and losing."
Thanks for that.
Other less notable performances will come from Coldplay, Leona Lewis, JLS, One Direction and the X Factor house band, Westlife.
