Louis Tomlinson will be going head to head with Simon Cowell tonight as his X Factor acts battle it out for to win the show.
Meanwhile media mogul Simon, 59, will be championing Scarlett Lee to singing her way to victory.
Fellow judge Robbie Williams, whose acts have all been knocked out, will be singing a duet with Scarlett tonight to that 90s classic Angels.
Dalton will be singing Beneath Your Beautiful with Emeli Sande while Anthony will be performing Leave a Light On with Tom Walker.
But why isn’t Louis performing with either of his acts tonight?
Back in July, both he and Robbie said that they were “definitely” up for singing a duet – together.
When Robbie was asked, he said: “I’d like to,” while Louis added: “When? Does that happen on the show?! Definitely up for it!”
Sadly, this idea never became reality but viewers had hoped they would take part in duets with their acts.
In the past, a number of judges have sung with their acts, including Tulisa and Little Mix and Gary Barlow with Marcus Collins.
However Louis likely hadn’t banked on having two of his acts in the final and choosing just one of them would have appeared like favoritism.
Who would you liked Louis to have done a duet with?
