Notorious bowtie-tweaker Cher Lloyd has revealed that her dis­tinct­ive grunt in certified US smash hit 'Want U Back' is a real one.

Speaking to MTV News, the 'Sorry Seems To Be The Hardest Word' singer said:

"I was in the studio, and for some reason, I couldn't hit a par­tic­u­lar note. I get really frus­trated with myself when I can't do something, so I made the 'ugh' sound, and they kept it in."

And so it came to be that one of the greatest pop noises in history was committed to 'wax'.

Well done everyone.
