Kourtney Kardashian Photo

Kourtney Kardashian is the least known of the older Kardashian sisters. She's probably the best looking, though.

Kourtney has never made a sex tape, nor has she ever posed naked for attention and/or PETA. She's pretty much best known only for appearances on Keeping Up with the Kardashians, and for her and her sisters' clothing line.

This K-named sibling graduated from the University of Arizona.

She got pregnant in the spring of 2009 because she forgot to take the pill before having sex with Scott Disick. Fortunately, she's milking this impending child for more money and attention than ever before.

On December 14, in fact, she squeezed out Mason Dash Disick, naming him after the family's clothing boutique. Isn't that nice?
