The first couple of heavy metal is splitting after 33 years of marriage, according to multiple reports Sunday.

Sharon Osbourne is pulling the plug on her marriage to bat-biting hubby Ozzy because she believes he has been cheating on her with a much younger hairstylist, said The Sun of London.

Ozzy — aka “the Prince of Darkness” and former lead singer of the group Black Sabbath — has recently been living in a Southern California hotel, The Sun said.

“Sharon went ballistic with Ozzy and accused him of having the affair” with 45-year-old celebrity stylist Michelle Pugh, said a source close to the couple.

“[Sharon] said she had suspected something had been going on for some time and now had proof.”

Ozzy, 67, and Sharon, 63, have teetered on the brink of divorce for years.

In 2013, she opened up about Ozzy’s substance abuse on the CBS daytime show “The Talk,” which she helps host.

“Everybody knows he’s been struggling with this his entire life. I never knew he was using prescription drugs,” Sharon said. “I knew he was drinking occasionally, but I didn’t realize the extent.”

In 2014, things apparently came to a head when Ozzy finally began trying to tackle his booze and drug issues.

In an interview at the time, Sharon recalled a nasty spat they had July 4 of that year — their 32nd wedding anniversary -— which nearly brought them to a permanent split.

“I would never have imagined our anniversary would be the start of one of the worst periods in our marriage,” she 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.’”

But the couple stayed together — and even now, some sources close to them say there’s still a chance they’ll reconcile.

It’s “sort of true” they’ve broken up, but “he’ll be back,” a source told People magazine.

Reps for Sharon and Ozzy couldn’t be immediately reached for comment.

They have three kids: Aimee, 32, Kelly, 31, and Jack, 30.

Meanwhile, Pugh, whose celebrity clients include Jennifer Lopez and Alicia Silverstone, has reportedly canceled a string of appointments.

She also has taken leave from her Los Angeles salon, Meche, due to a “personal emergency,” the store’s manager told The Sun.

Ozzy rose to fame as leader of Black Sabbath in the 1970s, and Sharon later replaced her father as his manager and eventually became his wife.

Among Ozzy’s infamous onstage antics was the time he bit the head off a bat in 1982.

The couple both later recaptured fame with the MTV reality show “The Osbournes,” which aired from 2000 to 2005.
