Kelly Osbourne settles lawsuit with dad's ex-mistress

Kelly Osbourne has settled a legal spat with her father Ozzy's former mistress.

Hairdresser Michelle Pugh accused the TV star of using her Twitter account to "paint a target" on her back "as a publicity stunt for financial gain" in a recently amended lawsuit.

Kelly tweeted Pugh's direct phone number and accused her of "elder abuse" after it emerged she had conducted a four-year affair with rocker Ozzy behind his wife Sharon's back.

The scandal rocked the couple's marriage, led to a brief separation earlier this year (16) and resulted in Ozzy seeking therapy for sex addiction.

Pugh claims she was targeted with abuse and became the victim of bullying after she was identified as the other woman in May (16).

She initially filed papers in August (16), accusing Kelly of publicly disclosing "private facts" and causing "intentional infliction of emotional distress".

But it appears she and the TV personality have settled their differences.

"The tweets have been removed and the lawsuit has been privately resolved," Pugh's lawyer Edie Mermelstein tells People magazine. "The resolution statement is mutual."

Kelly, who has yet to comment on the lawsuit or the reported resolution, originally wrote on Twitter in May, "Anyone looking for cheap chunky LOW-lights a blow out and a b**wjob call..." followed by Pugh's phone number.

When one user blasted her for blaming the stylist and not Ozzy, Kelly angrily replied, "are you in my family? NO YOU ARE NOT YOU HAVE NO IDEA WHAT SHE DID! So keep ur (sic) high-mighty opinions to yourself!"

Sharon was asked about Kelly's actions on The Talk and she admitted she found the tweets funny. She explained, "She loves her mom. She loves her dad so much... I'm always proud of my girl. What are you going to be mad (about)? She's an adult."
