Michelle 'Bombshell' McGee -- I Won't Ink a Sex Tape Deal

Michelle "Bombshell" McGee is trying to stop the porn company that snatched up her sex tapes ... threatening to sue if the videos go public.

As TMZ first reported, porn giant Red Light District says they are in possession of two separate sex tapes featuring Jesse James' former mistress -- one with a man, one with a woman.

But McGee's manager, Gina Rodriguez, has fired off a letter to RLD ... demanding they return the videos, which she says were stolen from Bombshell.

Rodriguez says McGee will sue if the tapes aren't returned ASAP ... and is asking RLD to return all copies and turn over the names of anyone who's seen it.
