A singing duo's audition for The X Factor ended with a punch when they rowed after criticism from Simon Cowell.
A spokesman for the television talent show said producers broke up the "heated" dispute between Abbey Johnston and Lisa Parker 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.
"It's sad but stuff happens," she told the Daily Mirror.
But Lisa told the newspaper she blamed head judge Simon's nasty comments for causing tempers to flare.
Lisa, 17, from Leamington Spa, Warwickshire, told the newspaper Simon described her performance of Journey's Don't Stop Believin' and Shayne Ward's That's My Goal as the worst audition in history.
The student said she remembered being hit, adding: "I think Abbey only hit me once but then a security guard grabbed her and another one pushed me against the wall so I couldn't get to her.
"If Simon hadn't been so nasty, this probably wouldn't have happened."
An X Factor spokesman said: "Things got a bit heated. Producers quickly stepped in."
