The truth behind Kylie Jenner’s full lips has finally been revealed. Despite reports of plastic surgery, the reality star’s pillow lip look is actually due to a series of steps, which include “pinching” and lip liner.

Kylie’s secret was revealed by Scott Disick on a recent episode of “Keeping Up With the Kardashians.” In the installment of the E! reality series, Scott narrates Kylie’s beauty routine while the 17-year-old goes through the steps of creating her perfect pout.

“Have you seen her do her lipstick?” Scott Disick asks Kendall Jenner of her sister’s process. “It takes like 40 minutes. And then she like pulls one lip, pushes one out.”

The video shows Kylie making a kissy face in front a mirror before using her fingers to push out her top lip. Although she doesn’t apply any lipstick, E! Online reports that she lines her lips and colors them in with “bold, dark lipstick.” Click HERE to watch the video on E!
