Sharon, 60, in her forthcoming memoir "Unbreakable" explained that Ozzy went wild earlier this year at their Buckinghamshire, UK, home while Sharon was in Los Angeles working, reported the New York Post.
Later, Ozzy, 64, sped off to a pub in an Audi R8 and aides found a note under the wiper from a dealer offering the Black Sabbath rocker drugs, while Ozzy was drunk inside.
In the book Sharon writes that she arranged to get rid of Ozzy's 800,000 dollars car collection, and sold the Audi and one Ferrari he kept in the US.
