Saturday's extended programme will include two performances from each of the seven remaining contestants. It has already been confirmed that Wagner Carrilho will be singing Radiohead's 'Creep', while Mary Byrne is lined up to sing U2's 'All I Want Is You'.
Speaking on Matt Edmondson's F Factor blog, the contestants said that they were excited about the upcoming live show and admitted that they were pleased with the theme.
"I actually like a bit of rock," said Cher Lloyd. "I like upbeat because I like to dance. I'm not a candle. I like to rock out." Meanwhile, Rebecca Ferguson hinted that she would be doing her first "upbeat" song of the series.
The Rock Week theme was first used last year and featured eventual winner Joe McElderry performing Journey's 'Don't Stop Believing' for the first time. Other highlights included Lucie Jones tackling Guns N' Roses, Jamie Archer covering Primal Scream's 'Rocks' and Jedward singing 'We Will Rock You'.
The X Factor starts on Saturday at 7.45pm.
