Following last night's breath-taking performances, the finalists who have scored the lowest in the public vote must face each other in the sing-off. Fighting for survival - they must sing to try and secure their place in the competition as one act must leave tonight.
Throughout the Live Shows an outstanding line-up of guest stars will perform. This week there will be performances from international star and performer Taylor Swift as well as one of former X Factor winners Little Mix.
