It's a two-part final, and the eventual champ will be announced tomorrow, but for tonight, we've got a jam-packed show full of rousing performances as the three finalists desperately try to win our votes.
Sam Bailey will be belting out Lady Gaga's 'Edge of Glory' as well as Jennifer Rush's 'Power of Love', before being joined by Nicole Scherzinger to sing massive hit 'And I'm Telling You'.
Nicholas McDonald will tackle Robbie Williams' hit 'Candy', and 'Angel' by Sarah McLachlan, and dueting with Westlife's Shane Filan on 'Flying Without Wings'.
Finally, Luke Friend will do 'We Are Young' by Fun, One Direction's 'What Makes You Beautiful' and is then set to be joined by Ellie Goulding for hit 'Anything Could Happen'.
At the end of the night, one will finish in third place, leaving the other two to fight it out on Sunday for the coveted title. Who will it be?
