News leaked in September that Jenner and Scott were expecting a child, though the Kardashian/Jenner family stayed tight-lipped about the pregnancy, often evading questions related to it.

Jenner, 20, also apologized for keeping fans in the dark, and said "my pregnancy was one I chose not to do in front of the world."

Kylie Jenner also posted an 11-minute video to YouTube called "To Our Daughter," which shows behind-the-scenes footage from throughout her pregnancy.

In it, she's shown telling her friends and family the news, going to the doctor, and eating In-N-Out Burger for two. Finally, the baby is born, at 4:43 p.m. on February 1.
