67-year-old Caitlyn Jenner, formerly known as Bruce Jenner, will be releasing a new memoir on April 25. The book, called The Secrets of My Life, promises various unveilings from the intimate life of the former Olympian. One of them, she talked about while promoting the memoir.

Referring to her male parts as “the damn thing”, Jenner says that she went for gender reassignment surgery in January of this year. “I just want to have all the right parts”, she wrote in a book excerpt obtained by Radar Online.

Jenner is, according to her own words, as enthusiastic about the change as she was 39 years ago, at the Olympics.

The former reality star adds that she finally came out with the information because she got too annoyed about intrusive questions from curious people. So, for her fans and for the rest of the curious world, she confirms the replacement of her male parts with female parts and this would be the only time she speaks of it. “You want to know, so now you know. Which is why this is the first time, and the last time, I will ever speak of it”, Jenner concluded.

On creating “The Secrets of My Life”, Caitlyn Jenner has collaborated with Buzz Bissinger, with whom she paired with for the 2015 article “Call me Caitlyn” in Vanity fair, which introduced Jenner as a woman to the public eye.

Bruce Jenner became Caitlyn officially in September 2015, when she legally changed her name. Earlier that same year, in July, she starred in her own reality series, I Am Cait. It was a short-lived project, as is was cancelled after two seasons.
