Sharon and Ozzy Osbourne could be separating after 33 years of marriage, according to reports.

The Black Sabbath lead singer, 67, has suffered years of alcohol and drug addition, with a relapse leading to divorce rumours in 2013.

Reports suggest their breakup is not related to substance abuse, but their spokesman only confirmed: "At this time Ozzy is not at the marital home".

The couple met in the 1970s after being introduced by her father, Don Arden, who was managing Black Sabbath. The pair wed in 1982 and have three children together: Jack, Kelly and Aimee.

The family rose to fame in the reality series 'The Osbournes', which ran from 2002-2005.
