The three hopefuls will take to the stage for one last time next weekend and sing their hearts out in the hope of being crowned this year's winner.
Bosses have now revealed exactly which two tunes each of the contestants will be belting out - and they're good 'uns!
Scots-born Nicholas will be singing 'Candy' by Robbie Williams and 'Angel' by Sarah McLachlan.
Prison officer Sam Bailey is hoping to impress the judges and the public with Lady Gaga's 'Edge Of Glory' and 'Power Of Love' by Jennifer Rush.
Meanwhile, Luke Friend - who found himself in the sing-off with Rough Copy last night - will be performing 'We Are Young' by Fun and his own version of One Direction's hit 'What Makes You Beautiful'.
Last night, after securing victory over Rough Copy, Luke shared a short Instagram video of himself, Sam and Nicholas as they celebrated making it to the final.
Luke captioned the video, "Guess what...I LOVE you guys so so much!!!!!!! #truefriendies @nickymcdonald11 @sambaileyreal", and it shows them screaming and jumping up and down.
