The Kardashian clan have done it all.

They have been the subject of countless magazine covers, starred on reality television shows, and have garnered an estimated $2 billion in worldwide revenue from licensing their music and likenesses.

Now, the sisters have created a new book titled The Secret Lives Of The World’s Most Famous Billionaires: How The World of Rockefdolls, Rocheffonds, and The Rockeffonds Became Rich.

The book will be published in March 2018 by Oxford University Press.

In the book, the rich and famous of the world, including the Kardashians and Rockefelds, discuss their life and their careers.

The title of the book refers to the “Secret Lives of The World,” a collection of essays that the rich have published over the years about their personal lives and the ways they built their fortunes.

“What makes The Secret lives of The Roccofonds, Rocfeldies, and Rockefolds the most amazing book?

Because it was written by the people who’ve made it the most extraordinary,” said book publisher and publisher of the memoir, Robert Shapiro, in a statement.

“The book is full of insightful insights into their lives and their successes and failures.

It’s a treasure trove of stories and anecdotes that will leave you awestruck by the lives of the people that we know.”
