In a new interview with People this past week, Kim made the revelation while promoting her new coffee table book, Selfish. She also said that the 17-year-old has been insecure about her lips since she was 10 years old.

Speaking about her sister Kylie, Kim said, "I saw how for so many years she was so insecure about [her lips]. 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."
