For the longest, 17-year-old Kylie Jenner has been denying the fact that she got any type of fillers in her lips, which out of nowhere looked crazy plump and full. She was saying it was simply “very good lip-lining” and just the proper use of her make-up, giving that crazy illusion of these big, beautiful lips. However, she finally cracked recently and admitted to having work done on her big puckers. Her big sister, Kim Kardashian, recently gave a heart-felt interview where she broke-down the real reasoning behind Kylie’s insecurities and lip fillers. “I saw how for so many years she was so insecure about it. I mean, at 10 years old, she would say to me, ‘How come my lips aren’t big like you guys’?’ And I would see this insecurity… For me, I gave her advice and I still stand by that advice. I think it changed her confidence so much,” says Kim. It’s all making a little bit more sense because everyone has their specific insecurities and if you have the money to fix it and feel better about yourself, by all means– go ahead! I’m sure it’s tough shoes to fill being the little sister of Kim, who is one of the most beautiful women on the planet. Do you think Kylie is too young to be getting work done?
