X Factor duets: Which stars did the finalists sing with in the final

And we all know that the most interesting thing about the (apart from the winner) is who the X Factor contestants duet with.

With stars such as Beyonce and Rihanna performing duets in the X Factor final in the past, the bar was set pretty darn high.

So who did the contestants sing with?

Kevin Davy White

Nicole Scherzinger's act, Kevin Davy White, was up first, performing with Britain's Got Talent winner Tokio Myers.

The pair performed a version of George Michael's Fast Love, with Kevin, 29 on the vocals (obviously), and Tokio on the piano.

The track went down well with fans, however some did think it was a bit unfair Kevin didn't actually get someone to sing with.

Some even speculated this was his downfall, with Kevin voted out of Saturday night's show.

Grace Davies

The Blackburn lass was next to take the stage with Paloma Faith.

The pair performed at a duet of the 20-year-old's original song Roots.

However, not everyone was a fan, judging by the Twitter comments.

One scolded: "Paloma Faith just ruined Grace's song."

While another added: "Talent vacuum Paloma Faith is going to suck all the fun out of this, isn't she? Poor Grace."

Crybaby star Paloma even called out Grace for being "bossy" after their performance – eek, totally awkward.

Rak-Su

The Watford manband had been rumoured to perform with Little Mix and Craig David.

However, Simon Cowell's act surprised everyone when they hit the stage with not one, but two star performers.

Rak-Su were joined by music producer Naught Boy and US rapper Wyclef Jean on their original song Dimelo.

Some fans thought it was a bit unfair the band had two acts to perform with.

However, their song, which they've performed on the show before, was a hit with fans.

All three tracks will be available on iTunes, with the profits going to Together for Short Lives and Shooting Star Chase.

The song will also be the champions winners single.

X Factor concludes on Sunday night at 7:15pm on ITV.
