It is true: Sex sells. Nothing hits the news stands faster than a good, old-fashioned celebrity sex tape. Or, in this case, a sex doll. These 10 creepy celebrity-inspired porn products have us questioning what our world is coming to:

Katy Pervy

Apparently, Katy Perry has done more than kiss a girl -- well at least in her porn spoof, Katy Pervy. The parody stars Kimberley Kane as Katy Pervy, a Ke$ha look-alike and an Elmo doll. Kinky! This is almost as creepy as her E.T. music video.

Crackhead Charlie: A Winning love doll

Inspired by Charlie Sheen, the Crackhead Charlie love doll is named after his infamous departure from Two and a Half Men -- it also sold out in one day. The box pokes fun at some of his best quotes:

"Just add air and this neurotic nutjob will show you his two and half personalities, warlock fangs, fire-breathing fists and Adonis DNA."

TMZ reported this Mischa Barton sex toy today. It was found in China and seems to be some sort of vibrating ring with her face clearly on the packaging. Sometimes you need a little Barton to get the night rolling.
