Ozzy Osbourne's Ex-Mistress Michelle Pugh Files Defamation Lawsuit Against Kelly Osbourne

By
Michelle Pugh is not taking Kelly Osbourne's comments lightly.
The 45-year-old hairstylist -- whose affair with Ozzy Osbourne rocked the singer's relationship with his wife of 33 years, Sharon Osbourne, earlier this year -- has filed a lawsuit against the couple's daughter after tweets she sent in May included Pugh's phone number and suggested the relationship with Ozzy, 67, amounted to "elder abuse."
According to court documents obtained by ET, Pugh is alleging Kelly's comments were defamatory, and that she has been "slut-shamed, bullied and harassed" by the Black Sabbath singer's daughter, adding the claim that Kelly "harnessed her celebrity and notoriety to incite her followers as well as the media machine."
Additionally, Pugh alleges that it was Ozzy who initiated their romantic involvement, and that the two dated in secrecy from 2013 until May of this year, while claiming that financial problems, and not the affair, drove Ozzy and Sharon apart.
The news comes after Ozzy revealed a years-long struggle with sex addiction.
“Over the last six years, I have been dealing with a sex addiction," Ozzy told ET in a statement on Wednesday. "I am mortified at what my behavior has done to my family. I thank God that my incredible wife is at my side to support me."
Ozzy also apologized "if Ms. Pugh took our sexual relationship out of context" after she called him the "greatest love of my life" in a recent interview with People.
"He made me feel like the most beautiful and worshiped woman in the world," she shared with the publication. "What attracted me to him? Chemistry. We just had it. It's that indescribable thing in life, and you can't deny it. And he didn't."
"Out of bad comes good," Ozzy added in his statement, in which he admitted to having multiple sexual partners during his marriage. "Since the press exposed this, I have gone into intense therapy."
Meanwhile, Ozzy said on Good Morning America last week that his marriage is "back on track," despite Pugh's claims that the couple had been unhappy.
