It could be a publicity stunt because there's no word of anything else coming out. There's no nudity but I wouldn't call safe for work. http://www.joblo.com/video/moviehotties/player.php?video=carmenelectra_leakedfootage My uneducated guess is that it's from a movie or a tv show that's still in production or in post production. I would be extremely happy to be wrong though.
Can we just assume that pretty much every woman in the public eye for whatever reason has a sex tape out there somewhere?
