Kourtney Kardashian pregnant Kardashian Konfidential book barner and noble hat autograph kendall jenner boots

The Kardashian girls certainly clean up well!

Khloe and pregnant sister Kourtney, who braved the rain hours earlier, hit up Barnes and Noble in Calabasas to sign copies of their book Kardashian Konfidential. We're lovin' those Louboutin boots, Khloe! Too bad soon-to-be-divorced Kim wasn't able to attend.

Although the coffee table book was initially released in November 2010, a deluxe version was just released last month and includes twelve never-before-seen photos from Kim and Kris Humphries' August 20th wedding. Also included in the new edition ... business advice from the Kardashian sisters.

Perhaps Santa will be throwing a few copies of the book down the chimney for the holidays. Ho, ho, ho!
