Simon Cowell has been Mr Nasty his whole life, says family

London (ANI): Simon Cowell has won international fame with his mean comments on talent shows. And now, his family has revealed that his malicious behaviour is not just restricted to his reel life-the music mogul has been 'Mr Nasty' his whole life.

The Britain's Got Talent judge's mother and brother have revealed that Cowell was feisty years before he was on TV. "He was a difficult child, he knew what he wanted and sent you barmy getting it," the Mirror quoted mum Julie as saying.

Brother Nicolas Cowell told TV's Where Did It All Go Right? on Five: "He was one of these children who made up their mind from a very early age and was very competitive as a child. Simon once reversed into the driveway and smashed into my dad's car breaking the glass. He picked up the glass and dropped it at the front of the house.

"He then let off the handbrake of dad's car and rolled it up to the glass and drove off. My mum was the last person to use dad's car, so Simon suggested mum had left the handbrake off! We were always in trouble, always doing something," Nicolas added.
