Ozzy and Sharon Osbourne split-up fears after 33 years of marriage
Ozzy and Sharon Osbourne may be splitting up after more than 33 years of marriage.
A spokesman for the couple said: "At this time Ozzy is not at the marital home."
The Black Sabbath frontman, 67, has fought a public battle with drug and alcohol addiction throughout their marriage.
He relapsed and this led to divorce rumours in 2013, but Mrs Osbourne, 63, stood by her husband.
Reports suggest their current separation is not due to substance abuse issues.
Mrs Osbourne, a former judge on ITV's The X Factor, detailed her reaction to her husband's relapse in her book, Unbreakable: My New Autobiography.
The star, who is a panellist on daytime US series The Talk, discovered he had relapsed as the couple celebrated 30 years of marriage.
"I would never have imagined our anniversary would be the start of one of the worst periods in our marriage," she wrote.
Osbourne and his wife met in the 1970s via her father Don Arden, who was managing the heavy metal group at that time.
Mrs Osbourne managed the Birmingham-born rocker before becoming his wife.
The pair wed in 1982 and have three children together: Jack, Kelly and Aimee.
Osbourne also has three children from his previous marriage.
The Osbourne family found a new level of fame when, with the exception of oldest child Aimee, they appeared in a television series together.
The Osbournes, the popular MTV reality show revolving around their lives, ran from 2002 to 2005 and became an instant hit.
It made the Osbournes household names around the globe.
As recently as last year, the family was in talks for a possible reboot of The Osbournes.
Mrs Osbourne did not appear on her US chat show The Talk amid reports she has split up with husband Ozzy.
Her co-host Julie Chen told viewers: "Now before we get started as you can see, Sharon is not here today. There were many tabloid headlines this past weekend about her and Ozzy. Rumours and speculation that they have split up after nearly 34 years of marriage.
"Sharon understandably took today off. We are sending all of love to her and to her family and we ask that you do the same."
