Jenner, who kept the pregnancy quiet, said she did it in order to maintain a calm environment for her baby.
"I'm sorry for keeping you in the dark all through the assumptions. I understand you're used to me bringing you along on all my journeys. My pregnancy was one I chose not to do in front of the world. I knew for myself I needed to prepare for this role of a lifetime in the most positive, stress-free and healthy way I knew how."
"There was no gotcha moment, no big paid reveal I had planned. I knew my baby would feel every stress and every emotion so I chose to do it this way for my little life and our happiness," she said.
Jenner has been with the father of her child, rapper Travis Scott, since April 2017.
TMZ first hinted at pregnancy rumors in September 2017.
