Los Angeles, May 21 (IANS): Fully supportive of her sister Kylie Jenner's decision to get lip fillers, reality TV star Kim Kardashian has said that the decision has changed the 17-year-old's "confidence so much".

“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,” accesshollywood.com quoted Kim as saying.

However, the 34-year-old eagerly advised Kylie to know when to stop when it came to plastic surgery.

"I think there are limits and there are boundaries, for sure. I think that you have to know the difference.

"She did something that made her feel better about herself and that's kind of where you have to draw the line, and she knows that. She doesn't have a desire to do anything else. I'm totally okay with that because I know that's where it stops for her,” Kim added.
