American reality television star Kylie Jenner has finally admitted that her lips are fake.

In a clip from the upcoming episode of Keeping Up With The Kardashians, the 17-year-old revealed that she has gotten lip filler.

"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 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," she said.

Rumours that Kylie has gone under the knife started after her lips in the selfies on her Instagram account looked plump and full.

However, she took to social media to deny lip augmentation reports.

Last month, many teens took up the Kylie Jenner Lip Challenge, an online trend where participants placed a glass or plastic cup around their lips and sucked on it for five minutes, resulting in a swollen, but bruised pucker.

Kylie responded to the challenge on Twitter and encouraged her fans to be themselves.

"I'm not here to try & encourage people/young girls to look like me or to think this is the way they should look," she wrote.

"I want to encourage people/young girls like me to be YOURSELF & not be afraid to experiment w your look."
