Jessica Simpson's little sis, Ashlee, didn't even pretend to mime along to her hit 'Pieces Of Me' on Saturday Night Live back in 2004. She just did it a little jig instead to try and distract us from the fact that she was going to mime along to her single. Yeah, that's do it, Ash.
Britney made hardly any attempt to hide the fact she was miming when she appeared on 'The X Factor' to perform 'Womanizer' in 2010. As if her out-of-time lip movements weren't enough, Dermot O'Learly gave the game away by handing Brit a mic to talk into after the performance. D'oh!
