Caitlyn Jenner has revealed she first attempted transitioning in the 1980s.

The former Olympian made the revelation in a video played at the Makers Conference in California on Tuesday (February 2).

Jenner revealed that she underwent hormone treatment and had even grown breasts – which she says she “loved”.

Despite beginning treatment, the fear of how people would react force the star to suspend treatment.

“I started on hormones. I was a good 36B. I loved them. I thought this was fabulous,” she said.

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

A few months later, Jenner met her ex-wife Kris – with whom she says she was brutally honest.

“We hit it off from day one,” Jenner recalled. “I was very honest with her. I had to be, I was a 36B.

“Everything was really heading in the right direction, and I made this decision to move on with my life, Kris and I together with this family.”

Although Kris accepted her new husband, their budding relationship forced Caitlyn to take some drastic action.

“I actually had my boobs removed. I never told anyone that,” Jenner said.

“The rules with Kris and I were, ‘Don’t dress up, certainly around the house.’

“If you really need to do that, when you’re on the road, take stuff and do that.”

However, Kris has previously denied her ex-partner’s allegations – claiming she only found out about Caitlyn’s earlier treatment a decade after they were married.

“Why would you want to be married and have kids if this is what you wanted since you were a little boy?” she said.

“Why would you not explain this all to me?”

Caitlyn’s eldest son Burt, meanwhile, says he has also known his father was trans, but was sworn to secrecy by his family.
