X Factor final: The song choices and guest performers have been revealed – and Adele and 1D WILL BE THERE

It’s the most wonderful tiiiime of the yeeeear – because the X Factor final is now just tantalising HOURS away, and we’ve just learned what the finalists are going to perform this weekend.

With the competition whittled down to three talented acts – Louisa Johnson, who’s been suffering from a mystery illness for the last couple of weeks, nan-favourite Che Chesterman, and are-they-actually-a-comedy-duo-or-what twosome Reggie N’ Bollie – it was time for the judges to pull out all the stops for the very last songs of the series.

So OBVIOUSLY one of them is going to be belting out some Spice Girls.

They'll also each be partnered up for a duet with a super-famous person, although ITV are keeping very tight-lipped about who's onboard probs because they're still in talks with them.

What are the X Factor final songs?

Che Chesterman

Our fave 19-year-old is going to be taking on Phil Collins’ excellent In The Air Tonight, which we’re really hoping is going to include that drum solo. He’ll also be singing the jazzy version of Valerie made famous by Mark Ronson and Amy Winehouse, so expect some swinging arms and lots of in-time finger clicking.

Mentor Nick Grimshaw has promised the person duetting with Che will be SO excellent that "everyone will be starstruck". Who could that be? Beyonce? Taylor Swift? Rihanna? She has got an album coming out very soon...

Louisa Johnson

Poor old Louisa is still on voice rest after suffering a particularly nasty illness, but she’s said she’ll be singing at the final if it’s the last thing she does. She’ll be doing Christina Aguilera’s Fighter (heart-eyes emoji x3) and I Believe I Can Fly by midget-bothering closet-dweller R Kelly.

Louisa's confirmed duet partner is her very own X Factor mentor, Rita Ora.

Reggie ‘N’ Bollie

Fresh from having to pretty much push their mentor Cheryl Fernandez-Versini off the stage to stop her stealing their limelight, Reg n’ Bol will be covering a mash-up of Spice Up Your Life (YASSS) and Outhere Brothers’ Boom Boom Boom, followed by a rousing rendition of Kriss Kross klassic Jump.

Both Sean Paul and Shaggy have been rumoured to duet with the lads, but Chezza says they're still nailing down their final decision.

Who's performing on the X Factor final?

It’s going to be an audible smorgasbord of a weekend, given that Adele has confirmed she’ll be performing on Sunday’s results show, belting out hit single Hello, while Coldplay will play Adventures Of A Lifetime from their new album A Head Full Of Dreams.

One Direction will turn up to smash out two of their new album tracks, Infinity and History, while Ben Haenow – yes, he's still going – will be around on Saturday night, performing Slamming Doors alongside 2006 winner Leona Lewis.

Oh, and also on Saturday's show, Little Mix will be performing with Fleur East.

SO MUCH MUSIC.

What's the 2015 X Factor winner's song?

Simon Cowell, in his infinite wisdom, has apparently chosen Bob Dylan's *Forever Young *for this year's Christmas no.1, and it's thought the proceeds from sales will go to charity. Which is nice.

What time is the X Factor final on?

You can catch it all on Saturday from 8pm on ITV1, then again for the same time on Sunday. 'Citing!
