Kylie Jenner: I use 'temporary lip fillers'

Reality TV star Kylie Jenner has admitted undergoing a cosmetic procedure to achieve the full lips that fans have tried to emulate in a way that physically harmed some.

"I have temporary lip fillers. It's just an insecurity of mine and it's what I wanted to do," Jenner, 17, says in a preview clip for Sunday's episode of E!'s "Keeping Up With the Kardashians."

"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," she insisted.

Jenner had tweeted on April 9, "These plastic surgery rumors hurt my feelings to be honest and are kinda insulting."

Fans seeking her look would suck on shot glasses, a tactic doctors warn could cause pain, swelling, bruising and possible scarring and disfigurement from broken glass.
