TMZ is reporting that Ozzy Osbourne's former mistress, Michelle Pugh, is suing Ozzy’s daughter Kelly, over several tweets that Kelly fired off after Ozzy's secret affair went public.

Says TMZ: “If you recall, Kelly blasted Pugh - a hairstylist - saying, "Anyone looking for cheap chunky LOW-lights a blow out and a b***job call [phone number]." She also accused Pugh of manipulating Ozzy - saying, "My father is almost 70 ever heard of elder abuse?" Pugh says she was "slut-shamed, bullied and harassed."

In her suit, filed in L.A. County Superior Court, Pugh claims the relationship was no fling - that Ozzy made advances and turned their friendship into a romantic situation in 2013. She claims they secretly dated until May 2016. Pugh says Osbourne's accusation that she committed elder abuse is not only wrong - but defamatory - and caused her all sorts of problems. Pugh says she's been emotionally damaged and lost business as a celebrity stylist.

In a new interview with People,  Michelle Pugh talks about her relationship with the Prince Of Darkness.

"When I say he gave me the greatest love of my life, I mean it," she claims after Ozzy first pursued her one year after she first colored his hair in late 2011. "He made me feel like the most beautiful and worshipped woman in the world."

"What attracted me to him? Chemistry," says Pugh. "We just had it. It's that indescribable thing in life, and you can't deny it. And he didn't."

Ozzy says that his relationship with Pugh was a purely physical one that resulted from his sex addiction. His rep says that he’s “gone into intense therapy and he apologizes to the other women he has been having sexual relationships with.”

"I still love him," continues Pugh. "And I would never exploit the truly personal and private parts of what we had. That's not me. I'm going to stand tall and proud and say, 'This is me. I'm not ashamed.' I fell in love with a man that gave me the love I never knew I could receive."

Ozzy claims that his marriage with Sharon is back on track.
