Blac Chyna denies that she was behind the recent release of a sex tape, an 83-second clip that shows her performing oral sex on an unnamed man.

Insiders say that Chyna shot it on her cellphone in July, but that she never showed it to anybody, according to TMZ. Sources also say that there is no evidence of a hack.

In related news, the model’s ex-boyfriend Mechie has said that he is the man in the video. He claims he shot it on her phone in July and that he never obtained a copy for himself, so he doesn’t know how it was leaked.

Upon the video’s release, Chyna’s attorney Lisa Bloom called it “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.”

Insiders say that Chyna will report the matter to police this week and that she intends on cooperating with authorities.
