x factor final guests

A whole host of guest stars have been confirmed for The X Factor 2015 final this weekend and Adele is topping the bill.

She will perform this Sunday night at Wembley Arena ahead of the crowning of The X Factor 2015 winner.

Here we give you a CONFIRMED run down of the X Factor final guest stars and just when they're performing this weekend.

X Factor final: Who's singing on Saturday?

Saturday night will be a VERY special show with a number of X Factor Alumni hitting the stage for some one-off performances.

Fleur East will become the fifth member of Little Mix as they sing together in a special collaboration, while former X Factor winners Ben Haenow and Leona Lewis will also perform a duet.

PLUS there will be the finalists duets. We know that Rita Ora and Louisa Johnson will be singing together but neither Che Chesterman nor Reggie n Bollie's duet partners have been confirmed and will not be until the live show itself.

X Factor final: Then on Sunday night...

Adele will be taking to The X Factor stage to perform her number one single Hello during the series grand final. This will mark the award winning singer’s first ever performance on The X Factor and follows the release of her record-breaking album 25, which was released last month.

In a celebration of the best of British music, Coldplay and One Direction will be joining Sunday night’s line-up of guest performers. Coldplay will be performing Adventure of A Lifetime from their new album A Head Full Of Dreams and One Direction will perform their latest single Infinity.

But wait, there's more!

Over the weekend there will also be a group performance from all of the finalists as they reunite together for one last time *SOB*.

The X Factor 2015 final airs this Saturday and Sunday night on ITV from 8PM.
