Kelly Osbourne is once again proving that she's no one to mess with. The youngest Osbourne and former host of E!'s Fashion Police, took to Twitter to publicly out her father's mistress. In a tweet posted on May 23, she put celebrity hairstylist Michelle Pugh on blast in a majorly epic way.

"Anyone looking for cheap chunky LOW-lights a blow out and a blowjob call +1(323)9202323," read the tweet, which has since been deleted from her timeline.

Sharon Osbourne, 63, publicly announced her split with Ozzy, 67, on her show The Talk back on May 10. The host and manager walked out on stage carrying a glass of lemonade as reference to Beyoncé's new album. 

Earlier this month, Us Weekly reported that Sharon discovered the affair after rifling through the Black Sabbath lead singer's emails and finding correspondence with the L.A.-based hairstylist and colorist (who has since been fired from her salon, Mêche Salon).

"I've been avoiding looking at any pictures or reading anything. I know what's going on," Sharon said. "I don't need to read about it and see about it because it's like putting salt in a wound. So I don't need to."

Don't worry, Sharon — looks like Kelly's got your back on this one.
