The beauty boss confirmed the news on Instagram with a lengthy statement where she apologised for all the ~secrecy~ (rightly damn so!) and explains why she kept it hidden from the world.
She also shared a snippet of a video documenting her entire pregnancy. The video includes commentary from bestie Jordyn Woods, throwback clips from when Momager Kris Jenner was pregnant with Kylie and an inside look at what she got up to (and ate) while she was pregnant.
Watch the full vid below and we dare you not to cry:
Despite knowing about the pregnancy for months (she didn't hide it *that* well), the internet is going MENTAL over the news and Twitter has erupted with hilar reaction tweets.
