Kylie underwent a massive makeover between 2013 and 2015, most noticeably in her lips, with her pucker going from thin-lipped to impossibly pouty seemingly overnight. Though the change seemed obvious, Kylie swore up and down that her suddenly plumper pout was just a result of growing older.
One reason the world called her bluff: lips actually thin, not thicken, with age. It wasn't until big sis Khloé Kardashian called her out on her fibbing on an episode of Keeping up With the Kardashians in May 2015, that Kylie came clean about her lip injections.
In November 2016, Kylie told Complex she lied because "I wasn't even 17 yet. What if I came out and said, 'Oh, yeah, I got my lips done'? What are all those moms going to think about me? These kids, my fans, they're going to think I'm crazy. I didn't want to be a bad influence. I didn't want people to think you had to get your lips done to feel good about yourself. But they thought it was crazier that I was lying about it because it was so obvious. I wish I had just been honest and upfront." She added, "When you first get them done, you're like, 'Oh, it could be a little bit bigger on that side.' I'd go back and be like, 'They went down' and think they could be bigger. But I went too far. It was very painful."
