The foursome performed an odd, europop-esque rendition of Queen's classic hit 'Don't Stop Me Now' but seemed to struggle with the arrangement.
After performing the song, the boys took a hammering from the judges.
Tulisa told the boys:"It pains me to say this and I know the audience will disagree with me, but I just wasn't feeling it tonight."
"I didn't agree with the song choice Louis, there was so much going on…all the faults are down to Louis."
And it wasn't just Tulisa who left the blame firmly in Louis' hands.
Gary Barlow then chipped in: "You are a good band, but Louis destroyed that… that was just a catastrophic song choice…it was just so dated."
"Since you've [Louis] been working in the business boy bands have changed."
Nicole Scherzinger then added: "I don't know if you guys were having the best time."
Undeterred, Louis praised the boys for their performance, promising the other judges that they would work harder next week.
Louis previously took boy band JLS all the way to the final in the 2008 series of the X Factor but has failed to repeat this in subsequent years.
Come on Louis, pull your finger out and give these boys a chance.
