Transgender reality TV star Caitlyn Jenner says she had breasts removed in the 1980s, after she met ex-wife Kris Jenner.

In a film made for the Makers Conference, Jenner revealed she had first attempted transitioning to a woman over 30 years ago, and in fact had size B breasts when she met her future wife Kris.

“I loved them,” said Jenner of her breasts at the time.

“My mission at that point was to transition before I was 40. I got to 39 and i just couldn’t go any further.”

Jenner said it was in that period she met then-Kris Kardashian, and the pair’s instant attraction further complicated her transition.

“We hit it off from day one, and I was really honest with her, I had to be, I was a 36B,” she said.

Jenner said despite the knowledge she had aspired to transition, Kris Jenner and herself decided to have a family and for Caitlyn to live as a man.

“I got off hormones and actually got my boobs removed. I’ve never told anyone that,” she said.

“The rules were don’t dress up around the house, if you really need to do that do it on the road and take stuff with you. So I did that.”

Caitlyn Jenner revealed her transition process in a highly watched Diane Sawyer interview in 2015, although this is the first time she has revealed she had breasts at the time.

Since her transition, Jenner has her own reality TV show, I am Cait, while Kris Jenner has moved on with new boyfriend, Corey Gamble.
