Following controversy over her performance at Glastonbury yesterday, a spokesperson for Dolly Parton has insisted that the star did not mime during her debut performance at the festival yesterday (29th June).

Despite love from the crowd, many people on Twitter suggested the veteran singer's vocals had been pre-recorded. Even celebrities and news reporters have weighed in on the debate. Sky News anchor Kay Burley wrote: "Oh, Dolly is miming. How disappointing." On the other hand, Stephen Fry rushed to Parton's defence, insisting that her vocals were not pre-recorded. "I think I know quite a lot about how TV is made," he tweeted, "why are people saying @DollyParton is miming? She's fooling me." Fry added: "Believe me, that is not miming. If it appears not always to lip-sync that's an HD live processor issue. You see it with news reporters."

A representative for Parton commented on the controversy late on Sunday (29th June) by insisting the singer's vocals were live: "she sings live. Some people don't know an amazing singer when they hear one."
