She clashed with Cheryl, branding her “stupid” and insisted to the judges she was “a human being, not a number.”

But the "Love Made Me Do It" singer told Ariel she was "scary" and "by the way you walked over to me I thought we were gonna have a scrap."

Ariel, who was 26 at the time, then told the judges to “shove a bit of metal right up their a--,” as she was escorted out of the studio by a burly security guard.
