Kourtney, Kim and Khloe Kardashian can now add author to their long and varied resumes. Their tome, entitled 'Kardashian Konfidential,' is a fun and breezy read that traces their childhood and offers lots of beauty and style tips. It's also teeming with photos and letters that the girls have penned to each other through the years. It seems their tight sisterly bond is not just for the camera. The trio spoke to PopEater in the middle of a hectic New York book tour.

Kim, you write in 'Kardashian Konfidential' how you had a hard time with your body as a young girl.
Kim: Kourtney used to torture me and think I was odd because I had big boobs. I was 11 when I got my period and I started developing. I would sit in the bathtub, take a washcloth, put it under really hot water and put it against my boobs and pray to God, please don't make my boobs grow any bigger. And Kourtney would be like, "Your boobs are so big and ugly!" She was so mean and then I would have to wear a bra and she would say, "Who wears a bra? That's so disgusting." It was so embarrassing.
