Someone's shopping around what they say is a Blac Chyna/Tyga $ex tape, and the leading lady is doing everything within her power to keep it in the can.
Blac Chyna's lawyer, Walter Mosley, tells TMZ Chyna will go after anyone who releases the tape ... with a vengeance.
A tape has been sent to media outlets and p0*rn companies ... we can't vouch for the identity of the stars, but the tattoos match.
As far as we know, so far there are no takers.
