Kelly Osbourne's wicked payback on Ozzy's mistress

Hell hath no fury like an angry Osbourne.

Kelly Osbourne is smack in the middle of the drama between her estranged parents, Sharon and Ozzy. On Monday, the 31-year-old TV personality really went there, posting the phone number of the Black Sabbath singer’s alleged mistress, celebrity hairstylist Michelle Pugh, on Twitter along with some unsavory words.

The post has been retweeted 348 times and has 859 likes (so far!), but not everyone is down with the former Fashion Police co-host giving out Pugh’s number. When one of her followers told her to hate her dad, not the other woman, Kelly fired back.

Kelly also insinuated that the purported affair wasn’t the rock star’s fault. She suggests that the woman took advantage of The Prince of Effin Darkness.

Earlier this month, Sharon, 63, and Ozzy, 67, announced their separation after more than 33 years of marriage. Soon after, details about his alleged affair leaked out. After taking a day off of work, Sharon addressed the drama on The Talk.

While she didn’t utter the words “cheating” or “affair,” the redhead walked onstage carrying a glass of lemonade in reference to Beyoncé’s latest album, which is all about an unfaithful husband. She told the audience, “I’m 63 years of age, and I can’t keep living like this.”

Ozzy and Sharon, who have three children, had the most awkward reunion ever a week later. She’s still Ozzy’s manager so she attended a press conference about Ozzfest. He hugged her in front of reporters and photographers; she looked pained.

Kelly, who grew up before our eyes on The Osbournes, has never been one to be shy about her opinions. When she left E!’s Fashion Police last year, it was amid a spat with co-host Giuliana Rancic, which turned pretty nasty.

For her part, Pugh — who works at L.A.’s swanky Mêche salon and has colored Jenifer Lopez’s hair — hasn’t spoken about the cheating scandal.
