As her sisters tell her in Keeping Up With The Kardashians, she has some of the most trustworthy friends.
But Kylie hiding her pregnancy meant that we couldn't follow her on the journey. In the video she posted, we got an inside look into her pregnancy, but aside from that Kylie has kept it pretty private.
For Halloween, Kylie decided to share a never-before-seen photo from her pregnancy, from Halloween last year. Ky dressed as ice, while her best friend Jordyn Woods fire.
Kylie had only ever posted headshots from that night previously, so it's so nice to see her looking like an actual angel while pregnant!
