Will Linda Thompson dish on her former marriage to Bruce Jenner in a tell-all book?

Find Out Why Kris Jenner Said Her Marriage To Bruce Seems Like It 'Didn't Exist'

Although the mother of former Hills star Brody Jenner, and his brother Brandon, has yet to announce news of a new book, a source recently claimed the Real Housewives of Beverly Hills guest-star has a story to tell.

"Linda has been writing it for years, but has held off publishing it because of Bruce's transgender secret," an insider told Life & Style on Thursday. "Now she can finally be truthful about everything, including how she feels about Kris [Jenner], Bruce's third wife."

Kris Jenner Admits She Knew About Bruce's Struggle Before They Married

Weeks ago, Jenner came clean about his gender transition into a female, and during his interview with Diane Sawyer on 20/20, both Thompson and Jenner's first wife, Chrystie Crownover, expressed their support. Meanwhile, Kris had "no comment" about Bruce's decision to become a woman during the special, but later told Us Weekly "everybody's super supportive" of Jenner, and said she was "really happy" for him.

Still, Kris's refusal to give a comment to 20/20 didn't sit well with Thompson, and she's reportedly ready to tell the world about Kris's deep, dark secrets.

"Linda blames Kris for making Bruce go back into the closet in the '80s," and has reportedly "heard all about Kris' wild side — the cheating, the partying, her days hanging with O.J. Simpson," the source disclosed.

No word yet on a possible release date for the unconfirmed book.
