Poor old Cheryl Cole suffered an epic live TV fail on this year's 'Stand Up To Cancer' show thanks to a major mic malfunction, but she isn't the first star to be shown up live on stage in front of millions.
Britney Spears wasn't exactly music to our ears when someone messed with her backing tape levels on tour and even the pop institution that is Kylie Minogue gave us a toe-curling performance thanks to an out of sync mic pack.
So sit back, relax and get ready to cringe - and laugh - at the expense of the stars who have suffered some of the biggest live performance fails ever caught on film...
It wasn't just the 80,000 strong crowd at Party in the Park in 2000 that got a good soaking thanks to the famous British weather - so did the technical equipment on stage, which meant that what Kylie was hearing in her radio mic was out of time to what the audience could hear. Cue an out of synch melody and a seriously peeved off Ms Minogue.
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.
We challenge you to listen to the entire four painful minutes of this compilation of Britney's live vocals from one of her old tours. And she's critiquing singing hopefuls on 'The X Factor USA'? Sheesh.
Britney's BIG comeback to the world's stage at the 2007 MTV Music Awards following her meltdown wasn't exactly triumphant. Mind you, on the basis of this performance, even if she'd rehearsed every day for the next twelve months we doubt she'd have been ready for the 2008 show either.
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!
Jessica Simpson's little sis, Ashlee, didn't even get 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.
Jessie J suffered a mic malfunction during a live performance of Fun's 'We Are Young' on 'The Voice' earlier this year and despite it being live telly, asked for the backing track to be started again because she couldn't hear the music.
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.
Never has 'null points' been more deserving in the entire history of Eurovision than when the 2003 British entry, 'Cry Baby' was murdered on stage by Jemini who were flatter than Tara Palmer Tomkinson's chest. Funnily enough, they were never heard of again.
Katy Perry: Singer, songwriter, dancer... recorder player? Errrm, no.
