This morning on Today, Kim, Kourtney and Khloe—while promoting their "sisterhood autobiography"/beauty and style advice book Kardashian Konfidential—said the worst part of "being famous for being famous" is not being recognized as the entrepreneurs they are.

Their book hits stores tomorrow, but a sneak peek highlights a few fun facts that are revealed within its pages, like the story of Khloe losing her virginity to an older man (when she was 14), how Kourtney organizes her baby's closet according to color, and that the infamous O.J. Simpson white Bronco police chase started at the Kardashian home.
