Multiple outlets have reported that the 67-year-old rock star has moved out of the couple's shared home.

"At this time, Ozzy is not in the marital home," Rolling Stone quoted a spokesperson for the couple as saying.

The cause of the split is unclear, but according to People, it has nothing to do with Ozzy's previous substance abuse and addiction issues.

"He's been using alcohol and prescription drugs for the past year and a half," Sharon said. "Everybody knows he's been struggling with this his entire life. I never knew he was using prescription drugs. I knew he was drinking occasionally, but I didn't realize to the extent."

Sharon and Ozzy Osbourne first met in the '70s when Sharon was working for her father, who managed Ozzy's band, Black Sabbath. Sharon later became Ozzy's manager.

The two were married on July 4, 1982. They have three children together -- Aimee Osbourne, 32, Kelly Osbourne, 31, and Jack Osbourne, 30.
