Caitlyn Jenner, formerly Bruce Jenner, has revealed a new secret. In a new clip from the Makers Conference, the "Keeping Up with the Kardashians" veteran explained the process of her transition into a woman which had actually begun since she was in her 30s.

Caitlyn revealed that she had grown breasts through hormone treatment in the past. She admitted that she did it for her own pleasure, though she had her boobs removed when she met Kris Jenner. "I started doing things to make me feel better about myself. I started on hormones. I was a good 36B. I loved them. I thought this was fabulous," she explained. "My mission at that point was to transition before I was 40. Got to 39 [and] I just couldn't go any further."

She also revealed the reasons why she changed her mind and decided to halt the transition. "Three or four months later, I met Kris. We hit it off from day one. I was very honest with her. I had to be, I was a 36B," she recalled. "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. "

She said that she put aside the gender things she had to build a good relationship with Kris, though her then-wife actually knew what really happened. "I got to get rid of these gender things and get off hormones and this and that," she explained . "I actually had my boobs removed. I never told anyone that."

To handle her unusual behavior, Caitlyn, who announced her transition from male to female in April 2015, made an agreement with Kris. "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.' So I did that for years," she revealed.
