The bottom 2 were Kimberley and Alisha. Simon voted to send Kimberley home, Dannii voted to send Alisha home, leaving the casting vote to Louis after Sharon refused to vote and announced that she was leaving the show. Louis voted for Kimberley, meaning that she was the first act to leave the show.
The theme for this week's show was UK number 1's and the songs the contestants sung were:
Kimberley: It's raining men
Andy: I don't want to talk about it
Futureproof: She's the one
Beverley: I will survive
Emily: I knew you were waiting for me
Leon: Can't buy me love
Same Difference: Tragedy
Niki: Nothing compares to you
Rhydian: I'd do anything for love
Sharon: (After finding out two of her acts are in the bottom 2) I don't have any advice for them 'cause what I've said so far has been no good. I think I'm going to go home now Dermot.
Sharon: (After finding out two of her acts are in the bottom 2) I don't think I can be allowed to say what I think because I'd be banned from national television forever.
This show was aired on judge Dannii Minogue's birthday.
