London: Popstar Cheryl Cole is under attack for miming her `live` performance on the superhit reality show `X-Factor`, where she judges new singing talent.
The `Parachute` hit-maker had promised to sing "100 percent live", but after initially denying the lip syncing allegations, show insiders admitted that she had pre-recorded
the song, reported Daily Mail online.
Cole performed her new single `Promise`, wearing a black leotard and ivory with biker boots, but the sexy routine was trashed by fans.
Viewers soon took to the Internet to say they were convinced that the `Girls Aloud` singer mimed her vocals during the performance.
This was Cole`s first performance since recovering from a serious bout of malaria, three months ago.
The 27-year-old was given a massive platform to promote her new single and the new album on the show.
ITV claimed the decision to pre-record the show was made as it was impractical for Cole to carry out her judging duties if she was also singing on the show.
They did the same when she had performed `Fight For This Love` on the show last year.
