Kylie Jenner is known for her voluptuous lips, but let's be real, her boobs seem to have grown over night too. So, what's the secret to Kylie's killer cleavage?

In a recent video posted to Kylie's new website, she get's candid about all of those breast augmentation rumors. And, to much of our surprise, Kylie's "girls" are all hers! She credits her awesome cleavage to the Victoria's Secret Bombshell bra.

Seriously, that's all she does? She just wear's the Bombshell? Can you guys hold on one second while I run to the mall real quick? I feel like this bra has been around for years and I'm just now realizing that it actually works. I mean, the Victoria's Secret website does say that the Bombshell "adds 2-cups", so I can see how it makes Kylie's boobs look so great.
