Cheryl Cole 'didn't mime on The Voice UK'

However, her publicist denied the claims, saying: "She sang live with a backing track."

Cole had reportedly insisted beforehand that she aimed to sing live on the show, with producers fearing that she would need an auto-tuned microphone.
A source added: "It would have been hard for Cheryl to have sung through the whole performance - it was such an energetic dance routine. But I'm sure people will be disappointed if they expected her to sing throughout."
The live performance saw Cole launch into a 10ft swan dive into the arms of her male dancers.
Cole has also dismissed claims made by Tom Bower that she had tried to manipulate Simon Cowell while on The X Factor.
