Sam Callahan has become the latest to leave The X Factor 2013 in tonight's results.
Yesterday evening was the fifth time the final seven acts performed, singing classic British tracks.
The flash vote is still out, with Dermot O'Leary revealing the two acts with the fewest votes both this evening.
Sam Callahan and Luke Friend were announced has having polled the fewest votes, placing them both into the sing off. It was the first time for both in the bottom two, and the first time this series any of the boys were in the sing-off.
The pair performed again for the judges, with Luke singing U2 hit I Still Haven't Found What I'm Looking while Sam sung Goo Goo Dolls track Iris.
It was then over to the judges to make their decision, starting with the pair's mentor Louis Walsh, but he opted to abstain, saying: "I'm not sending any of them home, I'm their mentor!"
Nicole Scherzinger said: "Luke, you sung your heart out and I really connected with you. Sam, that's what I've been waiting every week, but unfortunately the act I have to send home is Sam."
Gary Barlow added: "A good job Luke, I love your style... Sam, that was the best performance I've ever seen you do... with a work ethic like yours, you're going to go very far in life, but the act I'm sending home tonight is you, Sam."
Sharon Osborune concluded: "I am so angry with you Sam, for waiting this long to connect as a performer, but I'm really sorry, I'm going to have to send you home."
