Simon Cowell was a 'handful' as a child

Simon Cowell's mother has revealed that he was a nightmare child and she used to constantly worry about him getting up to mischief.

The X Factor judge used to torment his brother and was stubborn towards his mum, Julie.

The 80-year-old said: "He was a complete handful, into everything.

"Once, he shaved his brother's hair off. And he would not take 'no' for an answer. Then again, neither would I. It was a battle of wills."
