Kylie Jenner admits using temporary lip fillers: 'I didn't lie'

Kylie Jenner may have said she was "bored" with people discussing her plump pout, but apparently there has been something to the talk: The youngest of the "Keeping Up With the Kardashians" ladies has admitted to using lip fillers.

"I have temporary lip fillers, it's just an insecurity of mine and it's what I wanted to do," the 17-year-old says in a new clip from "KUWTK."

So, wait: People have been talking about her lip look for months, skeptical that it could be achieved with lip-liner and lipstick tricks alone. Why didn't she spill before now?

"I want to admit to the lips, but people are so quick to judge me on everything," Jenner says. "So I might have tiptoed around the truth, but I didn't lie."

Mmm-kayyyy ....

"Kylie decided to plump her lips, and I don't think there's anything wrong with that," sister Khloe Kardashian says to camera in another clip from the show. "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."

Clearly, Jenner didn't use the ridiculous DIY method -- sucking on a drinking glass -- that young women chose during the "Kylie Jenner challenge" that circulated on social media in April. That was the one where perfectly lovely "before" pictures were accompanied by post-suction "after" shots of nasty, bruised faces and jacked-up lips.

"I'm not here to try & encourage people/young girls to look like me or to think this is the way they should look," the trend-setter tweeted at the time, adding: "I want to encourage people/young girls like me to be YOURSELF & not be afraid to experiment w your look."

Of course, at the time she neither confirmed nor denied her own, ahem, experimentation.
