The X Factor 2013: Sam Bailey & Nicole Scherzinger Duet Interrupted By Voices Of Jedward?

The X Factor’s live final last night saw a glass-shattering, roof-raising diva-off between Sam Bailey and Nicole Scherzinger on the Dreamgirls hit ‘And I Am Telling You’ – but viewers were confused when a couple of voices could be heard in the background.

It has since been claimed that the voices belonged to Jedward – who were backstage preparing for their performance in the reunion of the show’s barmy army of “memorable contestants”.

Their mics appeared to be switched on during Sam and Nicole’s performance, and at one point it sounded as if one of them was singing a bit of Katy Perry’s song ‘This Is How We Do’ from her album Prism.

People have been speculating about it on Twitter – with many finding the whole thing hilarious.
