Video: awful – jessie j's ear-splittingly worst vocals ever

You really will not believe what you are hearing. International pop star Jessie J is one of the UK's geatest vocalists but she sounds jaw-droppingly terrible here. After her recent duet

online with young fan Tom Bleasby caused an internet sensation, we went hunting for other examples of her vocal prowess. We did NOT expect to find this. We're generally not fans of the

vocoder, but they definitely needed one here. Your poor ears will beg for mercy at the sounds that appear to be coming out of the superstar singer - a woman who was a judge on The Voice, no

less. Dogs will howl up and down the land and a few car alarms will probably go off. We'd say cover your ears but then you'll miss the full effect of this hilarious video. SCROLL

DOWN TO WATCH THE VIDEO  Luckily for Jessie (and our poor ears) this is a fantastically well done hoax of her smash hit featuring Ariana Grande and Nicky Minaj. Mind you, the voice might be

fake, but all those crazy facial expressions are totally Jessie's own! It's taken from a stunning live vocal performance that the Brit superstar did for In:Demand Live Sessions.

YouTube user TheKosmic8 has been posting cleverly dubbed versions of tracks by huge artists like Taylor Swift, Sam Smith and Iggy Azalea. Frankly the clever Kosmic person, whoever they are,

lip-syncs better than Britney. And it seems that Jessie herself is a fan of The Kosmic8's work, revealing that she cried with laughter when she heard it.
