I don't think Aguilera suits Rebecca, but the others are good choices! Can't wait

[Arron]

Christina Aguilera?
Really?

[Sharon]

cher and will.i.am? is that for real it's cheryl and will.i.am basically but +100 chavness

[Special]

why is cheryl up will.i.am's arse?

& lol at matt getting the best one

[Mathew]

Robbie Williams never fails to make a good duet performance on X Factor. One Direction seem to be the best act left too, so that should be the winning number of the night.

[Chris]

I knew they would do this again. Haha, some good people going on.

Robbie Williams never fails to make a good duet performance on X Factor. One Direction seem to be the best act left too, so that should be the winning number of the night.

rihanna is better than robbie williams lol

[Misawa]

Will.I.Am is awful. So it makes sense that he's guesting with someone similarly bad.

[Eoin247]

Will i am and cher, you'd think that they might give the weakest voice a better singer to compensate.

I suppose we can all guess what the songs gona be like...
