Sharon and Ozzy Osbourne became one of the most unlikely A-list power couples and their love story endured despite the many challenges thrown their way.

Ozzy Osbourne, Black Sabbath frontman and reality TV star, has died at 76, just two weeks after celebrating his 43rd wedding anniversary with wife Sharon Osbourne.

Before Ozzy Osbourne died last week, he had already finished an "uncensored" book about his life. The rockstar died aged 76, after a long battle with Parkinson's disease, but he made sure to put pen to paper first.
