Tonight sees another heart-breaking elimination.
Following last night's breath-taking performances, the finalists have had a nail-biting day waiting to find out who stays and who goes.
In tonight’s show the tension in the studio is palpable as host, Dermot O'Leary, tells the remaining acts who is safe and who has scored the lowest number of votes. The two acts will have to fight for survival - they must sing to try and secure their place in the competition, as one act must leave tonight.
Performing live on the show tonight will be pop superstar Katy Perry; and singer songwriter Robin Thicke.
