The world speculated for months whether or not Kylie was pregnant.
Despite the 21-year-old being out and about, the press couldn't concretely report that Kylie was expecting.
The ability to keep her pregnancy out of the public eye has seriously impressed her sisters.
Kim and Khloe gushed over Kylie in a clip from this Sunday's all-new Keeping Up With the Kardashians.
"The funnest game ever is the Kylie pregnancy game," Kim begins. "Why?" Khloe chimes in. "Just to see what people think," Kim says.
"There were pictures of her out on TMZ and she looked so skinny," added the mum-of-three.
Kylie enjoyed her pregnancy in private thanks to her family's support and clever fashion choices.
"Your pregnancy has been the best kept secret of our generation," Kim gushed to Kylie.
However, the new mum kept it real and admitted she wanted to keep her pregnancy under the radar for personal reasons.
"Like, I'm not trying to keep a secret, I'm doing this for myself," Kylie retorted.
"Your friends deserve awards," Kim added, "Cause seriously, now you know you have some real ones 'cause that never would've happened in my day."
Kylie really did have us guessing and we can't get over how gorgeous Stormi is.
