Jenner opened up about her decision in her new memoir, The Secrets of My Life, confirming that she had the surgery in January of this year.
"The surgery was a success, and I feel not only wonderful but liberated," she wrote in the memoir, according to Radar Online.
Jenner decided to be open about her decision in order to put an end to all the speculation, writing, "I am telling you because I believe in candor. So all of you can stop staring. 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."
The surgery definitely seemed like a huge milestone for Jenner, who wrote later, "I just want to have all the right parts. I am also tired of tucking the d*mn thing in all the time. I am going to live authentically for the first time in my life."
Jenner is currently gearing up for a nationwide book tour to support The Secrets of My Life, which will hit shelves on April 25.
