The revelations that Beyoncé lip synced her performance of 'The Star-Spangled Banner' at President Obama's inauguration on Monday left us all shocked, but let's be honest, she's hardly the first popstar to rely on the use of a backing track.
With her performances on 'The X Factor' and 'The Voice', Cheryl Cole has been a repeat offender, and who could forget when her backing track failed on 'Stand Up To Cancer' last year, exposing her as a mimer?
And then there is the Queen of mime, Britney Spears, who has been known to only sing one song live on her tours before now.
But the difference between them and Beyoncé is that we know the Destiny's Child singer can actually sing live, which makes her decision to lip sync at Obama's swearing in particularly odd. She's not even got the excuse of having to perform an energetic dance routine to defend herself with.
But credit where credit is due, she is blinking good at miming - we were totally fooled. This lot could learn a lot from her...
We always wondered how Cheryl managed to sing so perfectly whilst throwing some serious shapes to her No.1 single 'Call My Name'. Now, thanks to her performance on 'Stand Up To Cancer', we know.
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!
Mariah forgot to put her mic to her mouth in time for her big screechy note when she appearing on 'Ant & Dec's Saturday Night Takeaway'. Ooops!
All About Eve
We can't remember any of All About Eve's songs but we DO remember sitting down to watch Top of the Pops back in the day and seeing Julianne Regan and Tim Bricheno sitting there like lemons as their single 'Martha's Harbour' played but they failed to hear it. Despite the epic live telly fail, the single climbed the charts for the next two weeks!
If the acting work ever dries up for Li-Lo (which can't be that far off) you'd think she'd have her music *ahem* career to fall back on but she's going to need to brush up on her lip-synching skills first.
Cheryl Cole (again)
She may have prepared a backing track with live vocals recorded over the top, but Cheryl was fooling no one when she performed 'Fight For This Love' on 'The X Factor' in 2010.
Katy Perry: Singer, songwriter, dancer... recorder player? Errrm, no.
The 'X Factor' contestants
The 'X Factor' contestants have long made us cringe with their dreadful mimed group performances, but this particular rendition from 2011 had our toes extra curled.
Beyonce fooled us all with her rendition of 'The Star Spangled Banner' at President Obama's inauguration. And she would have got away with it if it wasn't for some pesky kids who outed her as having mimed.
