Kim, Kourtney and Khloe Kardashian stopped by the "Today" show Monday morning and dished on their family, their book and their dating habits.

The sisters have published a book called Kardashian Konfidential, an autobiography of the siblings' lives together, and the book is so unveiling that even its authors admitted to learning new facts about each other while writing it.

The girls combated claims that they are "famous for being famous," telling Matt Lauer that their father Robert instilled a work ethic into his children, and that they have each had jobs since they were 16.

Lauer also delved into the ladies' dating lives, asking Kim if she spends as much time alone as she has claimed. Khloe revealed that in the past Kim was a homebody but she has recently become "boy crazy."

Kardashian Konfidential is in stores now.
