Los Angeles - Caitlyn Jenner is writing a memoir.
The I Am Cait star is set to pen a tell-all book alongside journalist Buzz Bissinger, who conducted the first interview with the 66-year-old former Olympian where she first unveiled her post-transition self, and he has promised an "honest and open" look at her life.
Buzz told the New York Times newspaper: "I made it clear to her before I agreed that everything has to be on the table, nothing can be left out, and I'm going to be interviewing dozens of other people.

"It's her book, but it's going to be reported out to keep her honest. She's been incredibly open, and I think it has the potential to be a really important book."
In a statement released by Grand Central, Caitlyn added: "Things have been moving so quickly that it will be nice to slow things down a bit and take the proper time to reflect on this journey."
The book is expected to cover the entirety of Caitlyn's life, from her younger days when she was living as Bruce and achieved a gold medal at the 1976 Olympics through her three marriages - most recently to the matriarch of the Kardashian clan, Kris Jenner - as well as documenting her transition.
