The show previously had a Club Classics theme in the series 7 semi-final. That show featured Rebecca Ferguson covering 'Show Me Love', Mary Byrne tackling 'Never Can Say Goodbye' and One Direction taking on 'Only Girl (In The World)'.
Rylan Clark, who surprised viewers by surviving yesterday's elimination, has promised to "bring it" on Saturday night.
Meanwhile, bookmakers and Digital Spy readers' favourite Ella Henderson has claimed that she isn't daunted by the theme.
"I am so excited now for next week. I can't wait to start routining again because club classics is something I wouldn't do," she told Xtra Factor.

"But I can't wait to show people that I'm going to do something different."Boyband Union J commented: "We're going to pull something out of the bag, we've got the song down, we've rehearsed it all week. Now we're just going to make sure everything is on point like the styling."
MK1 added: "We have a few plans in the bag, we're thinking what would work well for us, we're thinking of something quite modern, but we want to bring back that urban vibe too."
