Little Mix has managed to spark some pretty angry reactions from fans after a live performance on Thursday night appeared to have been mimed. 

The popular girl band took to the stage at the BBC Music Awards in London last night to perform their hit single Black Magic. 

However, the girls received some pretty harsh fan feedback as it appeared that the track continued even when the girls did not have their microphones to their mouths. 

While the verses appear to have been sung live, it does seem that there was a heavy back track during the choruses. 

And their fans were less than impressed. 

Considering the amount of dancing these girls have to do, we are going to let them off this time. 

Judge for yourself and watch the video below.
