brightcove.createExperiences(); Kelly Osbourne isn’t a fan of her father’s alleged mistress.

On Monday night, the 31-year-old reality star took to Twitter to attack the celebrity hairstylist whose affair is rumored to have led to Ozzy and Sharon‘s split after 33 years of marriage.

“Anyone looking for cheap chunky LOW-light and blow out and a b—j– call …” Kelly wrote before listing a phone number that has since been disconnected.

Later, the former Fashion Police host slammed back at critics who suggested she turn her rage towards her father, ask “Are you my family? NO YOU ARE NOT YOU HAVE NO IDEA WHAT SHE DID! So keep ur high-mighty opinions to yourself!”

“Slightly hypocritical, don’t ya think?” Kelly added, asking why people were talking and commenting on her family drama while also slamming her for being open.

Kelly continued to respond to fans, claiming she blames the woman for the affair. “My father is almost 70 ever heard of elder abuse?” she wrote. (PEOPLE’s attempts to reach Ozzy’s alleged mistress for comment have been unsuccessful.)

“You may pee and tweet sitting down but your mouth is full of s—!!!!” she wrote to another critic.

This isn’t the first time Kelly has sent out public support for her mother. In the days after news broke of their split, Kelly posted a Instagram selfie of herself holding a lemon just hours after Sharon went on The Talk to address the divorce reports while drinking a “tall glass of Lemonade.”

“Guess who’s turning lemons into lemonade?” Kelly captioned the post – referencing the Beyonce Knowles breakup album of the same name.

Despite their split, a source told PEOPLE that Sharon and Ozzy are not discussing divorce at the moment. The pair recently reunited to promote Black Sabbath’s upcoming performance at the 20th-anniversary celebration of Ozzfest.

“I think I’m the strongest I’ve ever been right now, with everything that’s going on in my life,” Sharon, 63, said on The Talk. “I feel it.”
