Kylie Jenner finally copped to plumping her pout via lip injections -- something long assumed by pretty much everyone with decent vision and a penchant for celebrity gossip.

In a sneak peek for an upcoming episode of Keeping Up With the Kardashians posted on E! NewsKylie appears on-camera, admitting to temporary lip fillers. She said, "I have temporary lip fillers, it's just an insecurity of mine and it's what I wanted to do."

While Kylie's lips have been the subject of public speculation for quite a while now, the 17-year-old says that she didn't admit to getting lip fillers earlier because of the way her family is portrayed by the media. She said, "I'm just not ready to talk to reporters about my lips yet, because 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."

Kylie's referring to the time she -- pretty deftly, we have to admit -- said (quote via E! News), "I haven't had plastic surgery. I've never been under the knife. People flashback to pictures of me when I was 12 and say, 'Kylie's so different' but how can i look the same from 12-18?" And, like, she didn't lie -- lip injections do not require invasive surgery of any kind, so kudos for not technically lying, Kylie.
