Kendall and Kylie Jenner want their own reality TV show to feature all of the ''crazy stuff'' they do.

The 'Keeping Up With The Kardashians' stars want to feature in their own spin-off because they have so much fun working together.

Kendall told Seventeen magazine, ''We go on a lot of adventures! We do crazy stuff. We will kidnap one of our friends or get a group together and go to Disneyland for the night. We do what we want to do. We're just like, 'Let's make it happen!'

''Kylie is my best friend; we have so much fun. I also like working with her because she makes me more comfortable around people and I feel like she brings out the best In Me.''

The teenage sisters recently revealed they are working with co-writer Maya Sloane on a science-fiction story ''set 200 years in the future'' that they Hope to release next summer.

Kylie, 14, said: ''I think we will definitely get it done with how fast [the process] is going.''

Kendall, 16, added: ''We want to do something so different, something that we really love.''

The pair first brainstormed with their manager and mother Kris Jenner on the book and are now working with Maya on the first in a possible series for publisher Karen Hunter at Simon & Schuster.

The book will be aimed at young adults and will feature two sisters.
