Ozzy Osbourne was regularly high on drugs while shooting reality show The Osbournes.
‘The three years that we were filming, Ozzy was stoned the whole time,’ admits wife Sharon. ‘He wasn't sober for one day.’
Ozzy, 60, would secretly light up when the cameras stopped rolling.
‘I'd go in my little bunker and smoke a pipe and drink about a case of beer every day,’ he tells BBC Radio 2's Line Of Enquiry.
‘I'd give myself some goodness and get up early in the morning and go jogging for six miles. I used to do a lot of prescription drugs as well.’
The Osbournes came to an end in 2005.
