In a new teaser for this Sunday's episode of Keeping Up With the Kardashians, 17-year-old Kylie Jenner reveals that her plump pout is the result of lip fillers.

Kylie says in an interview:
    "I have temporary lip fillers, it’s just an insecurity of mine and it’s what I wanted to do. I’m just not ready to talk [about it yet]. Everyone always picks us apart. I want to admit to the lips, but people are so quick to judge me on everything, so I might have tiptoed around the truth, but I didn't lie."

Umm, ok Kylie, but let's not forget that interview you gave Cosmopolitan just three months ago where you claimed your new look was achieved by careful makeup application!

Prior to Kylie's not-so-shocking admission, we see a clip of her chatting with Khloe about the drama. After a reporter grilled Kylie about her new look, the teen reality queen says she'll never "deny or confirm anything," but Khloe goes on to confirm that her little sister has had a little nip tuck. "Kylie decided to plump her lips and I don't think there's anything wrong with that," Khloe says. "I think if you've done something though, it is right to cop up to it. If you avoid a question, you're going to look like a liar."

Well, the cat's out of the bag now! But since she's still a minor, don't you think someone should be taking the heat for this? You know, like mom Kris Jenner?
