The reality star, 18, opened up to Elle Canada about her most-talked about body part and why she finally admitted her pout was surgically enhanced.
"When I got my lips done, I literally told no one!" Jenner told the magazine. "I didn’t tell my best friend or even the guy I liked at the time. I really thought it was no one's business."
The youngest member of the Kardashian-Jenner clan admits her mother, Kris Jenner, was not immediately on board with her choice.
"My mom was super-against it, but I begged her and begged her and she finally let me do it," she said.

Initially, Jenner didn't comment about her lips because she felt her new look spoke for itself.
"After I did them, I thought it was so obvious that I didn't have to say anything," she explained. "I never denied it because I always told my publicist 'no lip questions,' so no one ever asked me. I never said I got them done, but I never denied it either. But people thought I was such a liar!"
The Keeping Up with the Kardashians star says she finally admitted to having lip fillers when the plastic surgery rumors started getting out of control.
"People were saying I got my chin reconstructed, that I got a nose job, an eyebrow lift, I got my boobs done, this and that," she said. "So I wanted to come out and say that this is crazy and I only got my lips done."
Jenner told the fashion mag that despite these rumors, she has not had any other plastic surgery.
"I don't think people realize that I just turned 18," she said. "There's no way my mom or any doctor would let me go under the knife like that – that's just so crazy!"
