Yesterday evening was the nine time the final four acts performed, singing twice for the second time this series, belting out classic hits by Elton John and Beyonce
Luke Friend, Nicholas McDonald, Rough Copy and Sam Bailey all sung for the judges and us viewers.
This evening, Dermot O'Leary revealed the two acts with the fewest votes in the latest live show.
Rough Copy and Luke Friend were announced has having polled the fewest votes, placing them both into the sing off. It was the third time in the bottom two for Luke, while the second time Rough Copy had to sing again.
The pair performed again for the judges, with Rough Copy singing Boyz II Men's End Of The Road while Luke sung Keane's Somewhere Only We Know
It was then over to the judges to make their decision, with Louis Walsh and Gary Barlow both unsurprisingly sticking by their own acts by voting to send Rough Copy and Luke home respectively.
Next, Nicole Scherzinger said: "Luke, you're such a diamond in the rough, there's no doubt in my mind that you're going to have a great career after this but the act I'm sending through to the final is Rough Copy.
With the casting vote, Sharon Osbourne said: "I'm going to put it to the public vote, so I'm sending Luke through."
With the judges' votes tied, it went back to deadlock and the act who received the fewest votes from the public and leaving the competition tonight was announced as Rough Copy.
The boys reacted: "Just being here is a highlight, we thank Gary for doing everything he's done for us, the whole X Factor team and our friends and family for being here the whole time."
