The X Factor finalists will be joined on stage by their mentors at the contest’s live final this weekend.
Kelly Rowland, Gary Barlow and Tulisa Contostavlos will all take to the stage alongside their respective charges at Wembley Arena during Saturday night’s show.
The judges have been secretly rehearsing their songs for the past week to ensure that they’ll be pitch-perfect alongside Amelia Lily, Marcus Collins and Little Mix when they face 10,000 screaming fans in the arena.
Kelly and Amelia are due to team up on a duet of Tina Turner’s River Deep, Mountain High, while Tulisa and Little Mix will attempt an Alicia Keys mash-up of Empire State of Mind and If I Ain’t Got You.
Gary and Marcus revealed today that they intend to perform a version of Billy Joel’s More Than a Woman.
Coldplay, Leona Lewis, JLS and One Direction are also set to make guest appearances during the show.
