Well this has to be one of the most cringe-worthy and toe-curling X Factor auditions of all time. Pals Abi and Lisa were all smiles and silly giggles when they first walked out on the stage, but it all turned a bit nasty when the crowd started booing. It's not often you witness an X Factor audition that ends in actual physical violence - but we aren't complaining. Fan your fingers over your eyes and have a watch...if you can bear it.
