Watch Kourtney Kardashian disses Kris Humphries on David Letterman's the late show.......hilarious!

It starts with Kim answering Dave's question when Dave think's Kanye West is a "young"man, Kim answer's "he's thirty five", hardly "young"!

When this little Kanye chat is over, THEN we get to see the gold Dave pans for us as the Kardashian girls, Kourtney included slamming Kim's ex husband,Chris Humphries.

Khloé is my favorite......she's the funniest and everything she says is hilarious and she's the realest of all the Kardashian sisters.
But Kourtney OMG,she's crazy!...never ceases to amaze me!

It's old news,but just watch and see the reaction Dave gets from the Kardashian sisters.
