Singer slated by fans for miming during performance

Cheryl Fernandez-Versini took to the stage on X Factor last night to perform her newest single, I Don't Care. The singer filmed a pre-recorded segment which was aired during the results show last night – but fans didn't approve.

Cheryl's sensational white outfit and high-octane dance moves weren't enough to disguise the fact that she seemed to mime for the majority of her performance.

Many viewers took to Twitter to share their criticism of the X Factor judge's decision to lip-synch:

Despite the negative reaction, Cheryl's rep claims she was indeed performing live. And the singer herself admitted she was suffering a serious case of the butterflies before going onstage. "It's natural to be nervous," she told presenter Dermot O'Leary afterwards. "I think it's healthy."

Cheryl's singing wasn't the only thing causing some shock, though. Her gaping white top left a number of fans wondering if they'd seen just a little too much more than they bargained for:

Hmmm, maybe stick to judging for now, Cheryl!
