A Blac Chyna sex tape has hit the net.

An 83-second clip of the model performing oral sex on an unnamed man was published on Twitter by an anonymous account on Monday (Feb. 19), according to TMZ.

Chyna’s lawyer Walter Mosley called this a “criminal matter” and has asked law enforcement to track down whoever posted the video. Meanwhile, her attorney Lisa Bloom tweeted about revenge porn.

“Revenge porn — posting explicit images without the consent of everyone in those images — is a crime, a civil wrong, and a form of domestic abuse,” she wrote. “It’s also a way to try to slut shame women for being sexual. Girls have killed themselves over revenge porn. It’s not a joke.”

Last year, Chyna threatened legal action after Rob Kardashian, the father of her daughter Dream, posted naked pictures of her online. Kardashian is not the man in the new video, according to the report.
