Ozzy Osbourne is one bad boy!

After splitting with his wife Sharon back in May, a rep for the rocker is saying that the reason he almost destroyed his marriage is because he's a sex addict.

"Over the last six years, Ozzy Osbourne has been dealing with a sex addiction," his rep told People.

In May, news broke that the Black Sabbath singer was having an affair with his hair stylist, Michelle Pugh. But his rep is claiming that the relationship wasn't romantic -- it was about his addiction, nothing more.

The rep also told People that Ozzy was, "Sorry if Ms. Pugh took their sexual relationship out of context. He would like to apologize to the other women he has been having sexual relationships with."

The rep also added that the father of three is getting intense therapy, and that he and Sharon have said they're working to save their 33 year marriage.

Unfortunately, Pugh didn't get Ozzy's memo --- since she's previously said that she felt as if the bat-biting rock star was courting her and that the relationship lasted four years.

Pugh says that their relationship, "felt like an old-fashioned romance. Being courted. I loved it." She said, "When I say he gave me the greatest love of my life, I mean it."

UPDATE: The mistress is suing Kelly Osbourne! Pugh filed a defamation, intentional infliction of emotional distress and public disclosure of public facts lawsuit against Ozzy's daughter over the tweets she wrote when their affair was exposed. In case you forgot, Kelly O put the hairstylist on blast when she learned her dad was cheating.

"Anyone looking for cheap chunky LOW-lights a blow out and a b***job call [phone number]," she vented on social media. "My father is almost 70 ever heard of elder abuse?" she added.

Pugh claims she was "slut-shamed, bullied and harassed," in the lawsuit. She alleges she has suffered emotional damages and has lost business as a celebrity hairstylist.

"I am not asking for anyone's approval, but the difference between someone's disapproval, and shaming and harassing publicly, that's verbal abuse. Everyone is entitled to their opinion, but you are not allowed to bully other people," Pugh tells People.
