Disgraced X Factor New Zealand judge Natalia Kills has been blasted by pop svengali Simon Cowell, who called her "mad" and "hateful".
"She sounded mad. It didn't even make sense," he told the Mail's Weekend magazine.
"Where they cocked up was that they didn't apologise straight away. If they'd both been genuinely sorry and called me, and apologised to the guy and his family, who knows what could have happened?They didn't. They were quite defensive."
Cowell is known as the original Mr Nasty in the UK, but the antics of Kills and Moon were too much for even him.
"It is sometimes a fine line, but there's a definite line and they crossed it. I don't think anyone's ever gone as far as that on any show we've ever made," he said.
