Kylie Jenner's baby girl was born on Feb. 1.

The Keeping Up with the Kardashiansstar's pregnancy -- her first, with rapper Travis Scott -- has been the subject of much rumor and speculation, but Jenner herself has kept quiet on the facts of the situation. Turns out, there's a reason for that.

"I'm sorry for keeping you in the dark through all the assumptions. I understand you're used to me bringing you along on all my journeys," she wrote in an Instagram post.

"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 know how. 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."

Jenner goes on to extol the "beautiful, empowering, and life changing" journey that was her pregnancy before revealing that her little girl was born on Feb. 1. She didn't share her new daughter's name; that's one detail you'll have to wait for.

She did, however, post a video on her YouTube channel documenting the youngest Jenner's conception and birth. If you thought the Instagram post was touching, wait until you watch this.

Congratulations to Kylie and Travis!
