After promising to sing live on The Voice, fans have accused Cheryl Cole of miming in her performance on Saturday night.
Dressed in a leopard-print top and colourful trousers, the Geordie star performed her new track Call My Name at the end of the talent show. But after she dived from a 10ft platform into the arms of 20 dancers and threw herself into an energetic dance routine, viewers were convinced she was lip-synching.
A source at the show said: "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."
While she received a standing ovation from the audience and judges, Will.i.am, Jessie J, Tom Jones and Danny O'Donoghue, TV viewers took to Twitter to accuse her of miming.
One tweeter wrote: "A bit embarrassing that she's gone on a singing show and mimed," while another said: "Blatantly lip-synching... Such an irony that she's performing on a show that promotes real talent."
Last night Cheryl's publicist said the star was singing into her microphone, adding: "She sang live with a backing track."
