According to E! News, Ozzy Osbourne and his wife of 33 years, Sharon Osbourne, have split up.

A source has told E! News that the couple mutually agreed that Ozzy would move out of their house temporarily.

The report states that the couple’s breakup is not related to Ozzy‘s sobriety. The BLACK SABBATH singer has apparently been sober for three and a quarter years.

British tabloid newspaper The Sun reports that Sharon left Ozzy after she accused the musician of having an alleged affair with a celebrity hairstylist.

The couple’s spokesman, Gary Farrow, did not address the infidelity claims, but issued the following statement to The Huffington Post U.K.: “At this time, Ozzy is not at the marital home.”

A source told People that the rumors of the split are “sort of true,” but added that they would not be surprised if Ozzy and Sharon worked out their differences. “He’ll be back,” the source said.

Ozzy, who relapsed into drug and alcohol abuse for 18 months a few years ago, has previously credited Sharon for saving his life. “I’m alive because I’ve got a strong wife, I think,” he said. “I didn’t expect to live past 30. I remember when I was 21 saying I would be dead by 40. That was all right until I was 39½.”

Sharon discussed Ozzy‘s last relapse during an episode of her U.S. talk show “The Talk” in April 2013. She said: “Everybody knows he’s been struggling with this his entire life and I never knew that he was using prescription drugs. I knew he was drinking occasionally, but I didn’t realize to the extent.

“It’s a disease that not only hurts the person that has the disease but it hurts the family. It hurts people that love you and we’re dealing with it. We’ve dealt with worse and we will deal with it and this too shall pass. Otherwise my husband will be taken to the hospital to get my foot removed from his ass.”

As part of his recovery, Ozzy was going to daily AA meetings which he said was the only way he can stay sober. “Sharon tells me I’m a bloody fool and screams at me when I’m drinking, but that doesn’t stop me,” he told “But she supports me, she knows it’s an illness, she knows it’s part of who I am and it’s only me who can deal with it and it’s because I don’t want to lose what I have with Sharon and the kids that I do it. No one else can cure an addict but the addict.”

After Ozzy was fired from BLACK SABBATH in 1979 because of substance abuse and erratic behavior, Sharon became his solo career manager, and then his girlfriend. The two were married on July 4, 1982.

The couple’s early relationship has been described as volatile, with Ozzy blacking out and almost strangling Sharon after a five-day Vodka binge in 1989.

Ozzy and Sharon have three children: Aimee, 31; Kelly, 29; and Jack, 28.
