X-Factor final - here is what we know already

The long-awaited X-Factor final takes to our screens this weekend. Perfect timing to put your feet up and save a little money before the festive season gets into full swing.

Here’s what we know already:

Ben Haenow and Fleur East have chosen the same 'X Factor' winner's single. The wannabe popstars - who are both mentored by over 25s judge Simon Cowell - have revealed they've both chosen the same song to release if they're crowned winner of the competition this weekend.

Quizzed by Ruth Langsford and Eamonn Holmes on ITV's 'This Morning' on whether it was true they'd both decided on the same track, Ben said: "Yes it's 'Something I Need' by OneRepublic."

Andrea Faustini - who is the last remaining act from Mel B's boys category - will be sticking to what he does best by releasing a power ballad if he comes in first place.

"I can tell? 'I Didn't Know My Own Strength' by Whitney Houston," he said.

It’s the same song that reduced Cheryl and Mel B to blubbering messes during the X Factor bootcamp stages.

Meanwhile, Andrea has also commented on reports Mel - who is said to have been struck by a mystery illness - could be set to miss the final altogether.

"Yes I heard that she's not so well but I think she be fine and it's okay," he said.

Also, according to reports, the three finalists Fleur East, Andrea Faustini and Ben Haenow will join Take That for a performance of Rule The World.

“It’s really unusual for producers to team up the final three contestants, as this is when they stand or fall as individuals,” A source said, speaking to The Mirror.

“But they wanted to spice things up. So rather than having them sing two songs each and a duet, they’ll each be performing a duet and then this collaboration.”

But who will take part in these infamous duets?

Rumours are rampant with performers such as Ed Sheeran, Meghan Trainor and Sam Smith are all making appearances.

Ed Sheeran will be performing 'Photograph' and Meghan Trainor and her Grammy-nominated single 'All About That Bass'.

Then Sunday's show features Sam Smith and a 200-person choir performing 'Stay with Me', One Direction treating us to 'Where Do Broken Hearts Go' and Olly Murs and Demi Lovato performing their duet 'Up'.

We have a feeling Andrea and Sam, Fleur and Meghan and Ben and Ed could be the winning combinations.

What are your thoughts?

Fleur is the favourite to win the show outright.
