TMZ is reporting there is a porn spoof regarding Keeping Up with the Kardashians. Ummm! I'm not sure I believe it's a 'spoof!' 
This is what TMZ had to say about it:

The Kardashians are being spoofed in a new porn movie and everyone from Kim to Kris is getting the XXX treatment. Not sure if there's really any demand for the spoof, for there is an ACTUAL sex tape with ACTUAL Kardashian you may have heard of or seen once or ten times ...
