Blac Chyna is feuding with another family member — but this time, it isn't one of Rob Kardashian’s sisters!

The 28-year-old model posted a long, expletive-filled rant on Snapchat directed at one of her own sisters. In the text post, she accused her sibling of stealing her credit card.

“Are you f–king serious this b—h stole my credit card,” Chyna wrote in her post. “All the sh– I do for her — if you wanted something just ask, I’m not stingy at all.”

She further explained that she does everything for her sister, including giving her money to get her hair and nails done and buying her new clothes and shoes. But she allegedly stole the card in order to buy things for her boyfriend.

“Sister or not, I’m done,” the mom-of-two wrote.

Chyna claimed she even let her sister stay at her house, but after she started bringing men over, she kicked her out. “Don’t come running to me when you need something,” the controversial star concluded.

Fans were introduced to two of Blac Chyna’s half-sisters during an episode of Rob & Chyna. Britney and Camille joined Chyna, her fiancé Rob, her father Eric, and her mother Tokyo Toni for dinner while she was visiting family in Washington, D.C., and things got pretty awkward when Toni found out that Chyna and her half-sister Britney are the same age.

The reality star is no stranger to feuds. Before she started dating Rob, she had a very public fight with his little sister Kylie Jenner after the teen started dating her ex-fiancé Tyga.
