It was the elective procedure heard 'round the world: In 2016, after heavy speculation, Kylie Jenner revealed during a Complex interview that she had, indeed, gotten lip injections. And in the latest episode of Life of Kylie, she revealed why.

"I was 15, and I was insecure about my lips," she said in the episode. "I have really small lips, and it was like one of my first kisses and a guy was like, ‘I didn’t think you would be a good kisser because you have such small lips.’ But I took that really hard. Just when a guy you like says that, I don’t know, it just really affected me."

Still, she said the choice was ultimately hers to make.

"I really wanted bigger lips," she said. "I would over-line my lips with lip liner just to create the illusion of bigger lips. And then finally I was like this lip liner isn’t doing it. I ended up getting my lips done."

Thankfully, she had the support of sister Kim, who noted in the episode: "I think if something makes you feel insecure, and you've been feeling that way forever, who doesn't want to look amazing...You only have one life, and what I've realized from what all of us have gone through is do what makes you happy."
