Temper tantrums are nothing new on The X-Factor but Saturday night's show takes things to a whole new level when two contestants come to blows on stage.
Viewers will see the pair, Abbey Johnston and Lisa Parker, storm off stage to a chorus of boos before they even get as far as singing.
But eventually they come back and try to wow the judges with their version of Shayne Ward's That's My Goal.
It does not go down well and Lisa responds to some gentle criticism from guest judge Natalie Imbruglia by demanding: "Who are you, may I ask?".
Judge Simon Cowell takes the pair to task, telling them they have "the worst attitude" of any contestants ever and things go from bad to worse as Abbey lashes out at Lisa before leaving the stage.
A show spokesman said producers broke up the "heated" dispute during auditions at Birmingham's LG Arena in June.
Abbey said she lashed out at her friend after Lisa falsely claimed she had the hots for judge Louis Walsh.
There are stormy times for one contestant who annoys Cowell when he admits to changing his name for a more rock 'n' roll version.
Storm Lee, or Lee Gardner as he was once known, came all the way from Los Angeles in a bid to make his name.
But Cowell clearly isn't impressed, telling him: "I'm not going to call you Storm any more, because I think it's a stupid name."
