Former athlete and TV personality Bruce Jenner’s former wife Linda Thompson is said to be writing a tell-all book to share her side of the story after he recently confirmed he is transgender.

Thompson, who has sons Brandon, 33, and Brody, 31, with the Keeping Up with the Kardashians star, was married to the Jenner for five years until 1986.

“Linda has been writing it for years but has held off publishing it because of Bruce’s transgender secret. Now she can finally be truthful about everything,” a source said, reports femalefirst.co.uk.

But Thompson is allegedly planning to trash Jenner’s third ex-wife Kris Jenner, whom he split from in October 2013 after 22 years of marriage.

The source said: “Linda blames Kris for making Bruce go back into the closet in the ’80s. This book won’t be pretty for Kris.”
