Rocker Ozzy Osbourne has admitted that his mind is so ravaged by alcohol and drugs he cannot remember when his first child was born.
"Black Sabbath" singer Osbourne said he "can't be sure" when his eldest daughter Jessica, by first wife Thelma Mayfair, was born, reports dailystar.co.uk.
Osbourne then went on to marry Sharon Osbourne, 58, and have three children, Aimee, 27, Kelly, 26, and Jack, 25.
He has been in rehab more than 10 times.
"When you're on the bottle, you don't realise you're as bad as you are. I sometimes wonder, what was I smoking at the time?," the 68-year-old said.
Though he now says he doesn't drink or take drugs.
