Following the X Factor press conference today, we have learn that Simon Cowell revealed that one contestant will leave at the end of Saturday’s show while another will be eliminated halfway through Sunday’s instalment.

It will be a very nervous time for the four remaining acts this weekend:

Matt Cardle.

Rebecca Ferguson.

Cher Lloyd.

One Direction.

It was also confirmed that one of the songs the contestants will sing, will be a duet with an established artist. These are the names of the artist confirmed:

Christina Aguilera.
Rihanna.
Robbie Willams.
Wil.i.am.

Matt Cardle will duet with Rihanna singing Unfaithful, Rebecca will perform ‘Beautiful’ with Christina Aguilera, Cher Lloyd will perfrom Where Is The Love/ I Gotta Feeling with wil.i.am and One Direction Will Duet with Robbie Williams singing She’s the One.

Sources have informed us that the contestants will also sing the song they performed at their audition on Saturday. This idea was introduced for the first time last year and we think it is a good one as we will get to here a full rendition rather that the few seconds we sometimes get in the auditions. Check out their original performance by clicking the song titles below:

Audition Songs
Matt Cardle: You Know I’M No Good.
Rebecca Ferguson: A Change Is Gonna Come.
Cher Lloyd: Turn My Swag On.
One Direction: Torn.

In addition the finalists will also perform the following songs on Saturday:

Matt Cardle: Here With Me by Dido.
Rebecca Ferguson: Just like a star by Corinne Bailey Rae.
One Direction: Your Song by Elton John.
Cher Lloyd: Boom, boom, shake the room/I whip my hair by Will/Willow Smith mash-up.
