Since the third series it has become time honoured tradition that the finalists get to perform a duet with an already established artist. Previous duets have seen the likes of Kylie Minogue, Take That, Michael Bublé and Beyoncé take to the stage with contestants but this year the show has gone all out on getting in big names for the duets.

It was confirmed by several UK media outlets that the duetting artists will be Rihanna, Christina Aguilera, Robbie Williams and will.i.am. However ITV have remained tight lipped on who will be duetting with who on Saturday night.

The confirmation on who’s with who has come today.. it goes..

Matt Cardle & Rihanna
Cher Lloyd & will.i.am
Rebecca Ferguson & Christina Aguilera
