Each finalist will sing a song of their choice before taking to the stage to perform a duet with their mentor. Then, the person with the fewest votes will leave the competition.
The remaining three will sing one last song in an attempt to win the public votes. But who will be victorious overall?
We've also got a special exclusive group performance from Jessie J, Sir Tom Jones, Danny O'Donoghue and will.i.am to look forward to, a guest slot from Michael Bublé and other performances from music industry greats too to round off an evening of brilliant talent.
