Kelly Osbourne is being sued by her father’s mistress.
Hairdresser Michelle Pugh, who had a four-year affair with Kelly’s dad Ozzy Osbourne, is seeking compensatory and punitive damages after Kelly tweeted Michelle’s personal number and wrote: "Anyone looking for cheap chunky LOW-lights a blow out and a b*****b call (sic)."
Kelly also wrote: "My father is almost 70. Ever heard of elder abuse?" and Michelle’s lawyer F. Edie Mermelstein, says she "is taking a stand against cyber harassment and bullying at the hands of Kelly Osbourne" with this lawsuit.
She told PEOPLE: "In the age of social media, reality TV and the internet, anyone, especially a celebrity can launch a global attack leaving an indelible and permanent stain on a chosen target, while inciting masses to demean, degrade, comment and harass.
"Kelly Osbourne, with over four million followers and a strong media presence, intentionally did exactly that to Michelle Pugh on Twitter.
"There are laws on our books addressing harm and damage to the reputation of an individual, as well as publication of a person’s private facts. In violation of California laws and Twitter rules and policies, Kelly Osbourne publicly exposed my client to hatred, contempt ridicule and disgrace."
In recently filed court documents, Michelle accuses Kelly of "slut-shaming" her.
The lawsuit states: "Not only had Plaintiff begun to be slut-shamed, bullied, and harassed for allegedly breaking up a marriage, but was wrongfully accused of a crime that further held her up to ridicule, hate, and shame."
Meanwhile, Ozzy’s wife of 33 years, Sharon Osbourne, 63, has revealed that the rocker is being treated for sex addiction.
Sharon – who has Kelly, 31, Aimee, 32, and 30-year-old Jack with Ozzy, 67 – said: "After the (Black Sabbath) tour, he goes into inpatient for three months.
"He’s working at it. It’s hard because it affects the whole family. And, it’s quite embarrassing to talk about.
"Somehow drugs and drink is more acceptable I think. When it’s somebody that has a sex addiction, it’s embarrassing.
"He’s come out and admitted it finally. It’s very, very hard. It’s been going on for at least six years."
