He is 'fighting baldness' but has ruled out a Wayne Rooney-style hair transplant - insisting he would shave off his barnet if time took its toll.
"Someone said I'd had a hair transplant. There is definitely nothing wrong with doing that but I don't think personally I would," the Daily Star quoted him as saying.
"If I do start showing signs of going bald, then I will shave it off. I've still got hair. I'm still fighting it," he stated.
And he said watching Brooklyn, 12, Romeo, nine, and Cruz, six, getting older was "great but scary".
"Scary because I can see Brooklyn getting different interests, wanting to go out with his friends, wanting to talk about girls, growing up into a young man," he revealed.
But he is relieved six-month-old daughter Harper will have big brothers to look after her.
