Kardashian will work with her siblings Kourtney and Khloe to put together the book, which will include "tips and stories", as well as dating advice, reports dailystar.co.uk.
"My sisters and I are writing a book. It's going to have lots of fun tips and stories and everything about relationships. It is a little bit more of an in-depth look into our lives, even though people think that they have probably seen everything," said Kardashian.
"We are just being super-candid and sharing lots of pictures and fun stuff," she added.
