The life of Kylie Jenner has just changed, big time.

After months of speculation, the reality TV star and makeup mogul finally confirmed her pregnancy -- with her baby's birth announcement. Jenner posted a message on Instagram Sunday welcoming her "beautiful and healthy baby girl" and explaining why she and boyfriend Travis Scott chose to be so uncharacteristically private during her pregnancy.

"I'm sorry for keeping you in the dark through all the assumptions," she wrote. "I understand you're used to me bringing you along on all my journeys. my [sic] pregnancy was one I chose not to do in front of the world. I knew for myself i [sic] needed to prepare for this role of a lifetime in the most positive, stress free, and healthy way i [sic] knew how."

Jenner went on to describe her pregnancy as the most "beautiful, empowering, and life changing" experience she has ever had and also to thank her friends and family for helping her maintain her privacy. The "Life of Kylie" star then threw fans a bone by giving them a couple of details about her daughter -- namely, the fact that she was born on Feb. 1 and is "beautiful and healthy."

Jenner shared even more in a YouTube video posted to her channel Sunday. Called "To Our Daughter," it features footage from Jenner's pregnancy, interviews with friends, and even audio from the delivery room. If you stick it out to the end, you'll be rewarded with footage of the newest member of the Kardashian-Jenner clan, whose name we still don't know.

We're sure we'll be seeing much more of this little girl in the months and years to come.
