X Factor 2013 judge Sharon Osbourne lost her temper with Jonnie Rocco during this year's auditions, throwing a pen at the 73-year-old.
It was Jonnie's second time auditioning for the show, having waited until Sharon's return to the panel for another shot.
Having first fallen at the audition stages in 2007, things didn't go much better for him this time around after singing Elvis’s An American Trilogy for the panel.
With a slating from the judges, including Sharon, Jonnie quipped: “You think Ozzy can sing?”
But an angry Sharon threw her pen at him and stormed: “Get him out of my f***ing room.”
An X Factor insider told The Sun newspaper: “Jonnie hit a really raw nerve and Sharon was furious.
“Normally she takes criticism from contestants on the chin.
“But she and Ozzy have obviously been through a tough time this year and any negative remarks about him are like a red rag to a bull as far as she’s concerned.”
After last week's try outs in London, the judges will go on to hold the last audition stop this year in Cardiff. This will be followed by the second stage of judges’ arena auditions in July.
The show will return to our screens on ITV in August.
