One of the original celebrities to take hard partying, sex, drugs, and rock n roll to their absolute limits, Ozzy Osbourne has had a history with addiction that few can match. Admittedly spending close to 40 years of his life intoxicated in one form or another, the rock icon has struggled with alcohol and cocaine mostly. It is widely believed that Osbourne had been clean and sober for most of the last decade, but it was recently reported that Ozzy suffered a relapse this year.
