"The X Factor" UK 2015 grand finale is just a day away. Finalists Louisa Johnson, Che Chesterman and Reggie N Bollie will perform live for public votes one last time on Saturday before the winner is announced on Sunday night.

Finale spoilers:

Reggie N Bollie, Che Chesterman and Louisa Johnson will perform two songs each at Wembley SSE Arena on Saturday. They will sing their favourite number of the series and are also set to perform a duet with a celebrity guest. The top two acts will sing their winner's singles on Sunday night before the winner is declared.

The finals weekend will see performances from big names like Adele, Coldplay, Leona Lewis, Fleur East, One Direction, Little Mix and Ben Haenow.

Song choices:

Louisa Johnson of Rita Ora's GIRLS will sing "Fighter" by Christina Aguilera and "I Believe I Can Fly" by R Kelly.

Che Chesterman of Nick Grimshaw's BOYS will perform "In The Air Tonight" by Phil Collins and "Valerie" by Mark Ronson, featuring Amy Winehouse.

Reggie N Bollie of Fernandez-Versini's GROUPS will perform a mash-up of "Spice Up Your Life" by Spice Girls and "Boom Boom Boom" by Outhere Brothers, and "Jump" by Kriss Kross.

The two finalists will perform their winner's single on Sunday and it is still not known which sing they will be given.

Winner prediction:

It seems like the writing is already on the wall for the winner of "The X Factor" UK 2015. Louisa Johnson, 17, is no doubt the favourite to win this season's title. Judges, especially the otherwise hard-to-please Simon Cowell, have been singing her praises for a while now. Of course, she has been consistent throughout the competition, except in the quarter-final when she was unwell. Her performance last week was beautiful, making her the favourite to win the title this year.

Che Chesterman and Reggie N Bollie can't be ruled out, though. They can bounce back stronger in the finale and turn the tables. Anybody can be the winner.

Will Louisa Johnson miss the finals?

Louisa has had a period of bad health of late. She had throat infection two weeks ago, affecting her performance in the quarter-finals. It is reported that she is unwell again and could even miss the finale if her health doesn't improve.

"So sorry that I'm missing tonight in liverpool! Need to be on strict voice rest ahead of the biggest week of my life, it needs to be perfect, (sic)" tweeted Louisa on Wednesday.

She was voted through to the semi-final despite her poor rendition in the previous week due to a sore throat, but it will be a different story altogether in the finale if her bad health gets in the way of her performance. It is to be seen if she will recover fully before the finals.
