Kardashian Sisters Dip Into Childhood For New Book

Kim and Khloé also give fans advice in 'Kardashian Konfidential.'

Have you ever wondered what the early life of the Kardashian sisters was like? Or, have you ever wanted some advice on how to be more Kardashian-like in your own life? Well, the sisters just released a new book, "Kardashian Konfidential," to give their fans the lowdown on all things Kardashian.

"We felt like everyone probably assumed that they knew everything about us by watching the show ['Keeping Up With the Kardashians']," Kim told MTV News while promoting the book in New York. "But there's so much more to us, and our childhood is a huge part of what made us into the girls that we are today. So, we wanted to share fun pictures and stories just about our childhood and how we were raised."

Khloé added that a big part of the book focuses on their father, lawyer Robert Kardashian, who passed away in 2003 and rose to fame as one of the lawyers involved in the O.J. Simpson trial in the '90s.

"I also think that we really wanted to show how much our father influenced our lives," Khloé said. "And he was such a strong hand in making us who we are and business savvy, we just wanted everyone to promote that."

While the sisters are giving advice to readers, they revealed they often advise each other as well. "We give each other advice all the time," Kim said. "Just as sisters, we give advice back and forth all the time."

While they are busy promoting their book and working on their latest TV project, the sisters, specifically Kim and Khloé, will stage online deaths Wednesday in connection with World AIDS Day.

"Alicia Keys' charity asked Khloé and I to be involved, and we gladly would do anything," Kim explained. "The cause is really important to our heart."
