Blac Chyna is super mad today because a sex tape starring HER has leaked online…

TMZ.com says that her ex, Rob Kardashian, is NOT the guy in the tape even tough the man’s face is never shown in the video.

“The 1 minute, 23 seconds long clip was first posted early Monday morning by an anonymous Twitter account.”

Chyna has activated her legal team and they are actively trying to have the video removed from the internet.
