Kim Speaks Out: 'People Don't Know the Truth'

Flanked by bodyguards, two-thirds of the Kardashian sisters greeted fans and signed copies of their book Dollhouse at a Barnes & Noble bookstore in the Big Apple. The novel, which was written by Kourtney, Kim and Khloe, explores the high-profile lifestyles of reality TV's most popular families. Something tells me they probably left the chapter about Kim's 72-day marriage to Kris Humphries on the publishing floor. Now that I mention it, that part wouldn't have been longer than a prologue anyway.
