Kim Kardashian Talks Butt X-Ray With David Letterman

Kim Kardashian and her sisters, Kourtney & Khloe were on David Letterman last night n David didn't seem to know who the other 2 sisters were. For shame Dave. Although most of America doesn't know them as well as Kim either.

They were on there to discuss their clothing line for Sears called the "Kardashian Kollection" a little play with K's eh? Soon talk went more to Kim's butt x-ray instead of her wedding surprisingly.

After talking about Kim's butt, Dave was happy to "get to the bottom of that" n I can't believe Dave went with that. Check the clip above..if you dare or care.-Dr.FB
