The remaining acts will have to try and win over both the studio audience and viewers at home as they take centre stage to sing for their place in the competition.
This weekend will see a lot of mash-ups, which of course tie in with the theme for the contestants to reinvent themselves. But will the judges - including Simon Cowell - be impressed on the night?
