Kelly Osbourne posts number for father's mistress on Twitter

Kelly Osbourne has turned on the hairdresser allegedly at the center of her parents' marriage crisis by posting her phone number on Twitter.

Her dad Ozzy Osbourne's reported fling with Los Angeles-based stylist Michelle Pugh is the cause of his split with wife and manager Sharon, and the couple's daughter is out for revenge.

"Anyone looking for cheap chunky LOW-lights a blow out and a b**wjob call..." she tweeted on Monday (23May16), along with a Los Angeles phone number believed to be that of Pugh, who went into hiding as news of her alleged affair with Ozzy broke earlier this month (May16).

One follower called out Kelly for not putting more blame on her father, writing, "hate your father not the woman.. HE did this 2 ur (sic) family ... Again. #childish".

But the TV presenter fired back at the user and wrote, "are you in my family? NO YOU ARE NOT YOU HAVE NO IDEA WHAT SHE DID! So keep ur high-mighty opinions to yourself!"

Sharon, 63, initially kicked her 67-year-old husband of 34 years out of the family's Los Angeles home after learning of his fling, but she then moved out when Ozzy demanded to return.

Kelly has stuck by her mum's side ever since the news of her father's alleged infidelity broke, and she has been accompanying her to her chat show The Talk, according to reports.

And during an episode of The Talk in February (16), Sharon revealed she caught her rocker husband in bed with two of their children's nannies years ago.

Sharon confessed, "I caught two of them in bed with Ozzy different times. And it goes on and on and on."

When co-host Sara Gilbert suggested Sharon point her anger at the Black Sabbath frontman instead, Sharon quickly denounced the idea, alluding to the fact Ozzy was under the influence of drugs and alcohol at the time of his infidelity.

"No way!" Sharon exclaimed. "He was out of his mind. He's calling me his first wife, he's calling them me, He don't (sic) know!"

Eventually, Sharon learned from her mistakes and went with a sure fire way to avoid Ozzy being tempted - a male caretaker. She said, "At the end of the day, I hired a nanny called Big Dave."
