Sharon Osbourne and husband Ozzy Osbourne have reportedly called it quits after more than three decades of marriage.

According to a source, Ozzy and Sharon, who previously served as a judge on America's Got Talent, mutually agreed to part ways, E! News reported.

Ozzy, 67, has temporarily moved out of their house and into a Southern California hotel, but the breakup reportedly has nothing to do with drugs, as the heavy metal rocker has been sober for about three years now.

The Sun of London reported that infidelity is the cause of their separation. Sharon, 63, allegedly believes her husband had been cheating on her with 45-year-old celebrity stylist Michelle Pugh.

"Sharon went ballistic with Ozzy and accused him of having the affair," an insider told the newspaper. "[Sharon] said she had suspected something had been going on for some time and now had proof."

Divorce rumors first surfaced in 2013. After Ozzy wrote on Facebook, "Just to set the record straight, Sharon and I are not divorcing... I'm just trying to be a better person," Sharon assured fans on The Talk that tabloids tend to drastically distort "a little seed of truth."

And then the following year, Ozzy reportedly began to address his substance abuse issues but a nasty fight ensued in July 2014 -- which was when they celebrated their 32nd wedding anniversary -- which almost caused their marriage to crumble.

"I would never have imagined our anniversary would be the start of one of the worst periods in our marriage," Sharon had told the Daily Mail. "I thought, 'I can't carry this anymore. It's what I have always done and I'm tired.' I said, 'I want a divorce.'"

However, the couple worked through that tough time, and according to multiple sources, there is a chance they could still reconcile.

It's "sort of true" they've broken up, but "he'll be back," a source told People.

Sharon and Ozzy met in the early 1970s when he was a member of the band Black Sabbath. The pair wed on July 4, 1982 and later welcomed three children -- Aimee Osbourne, 32, Kelly Osbourne, 31, and Jack Osbourne, 30.

Everyone in the family, except for Aimee, starred on the MTV reality show The Osbournes between 2002 and 2005. Sharon later judged America's Got Talent from 2007 to 2012.
