Sharon Osbourne apparently flew into a rage when a 73-year-old X Factor hopeful insulted husband Ozzy's singing.
Jonnie Rocco - who had previously auditioned for the show in 2007 - failed to impress the judges with his rendition of Elvis's An American Trilogy. But when Sharon told him he wasn't going through to the next round he retorted: "You think Ozzy can sing?"
Sharon - who has been married to the heavy metal rocker for 31 years and is also his manager - launched a tirade of foul-mouthed abuse at the OAP and threw her pen at him, according to The Sun.
Jonnie, who auditioned in Manchester last month, was taken away by security under Sharon's orders. He had clearly gone too far by insulting her husband's talent.
When he was turned away from the singing contest by the judges in 2007 he apparently issued a mob-style death threat to Louis Walsh.
