(Cover) - EN Star Style - Kourtney Kardashian tries to stay positive about her appearance for the sake of her younger sisters.

The American reality TV star found fame thanks to show Keeping Up with the Kardashians, which stars her sisters Kim and Khlo and the rest of their family. The three siblings mother Kris married Bruce Jenner following the collapse of her marriage to their father Robert Kardashian. Kris and Bruce have daughters Kendall, 15, and 13-year-old Kylie, who Kourtney is close to.

She knows there is a great deal of pressure on the youngsters because of the fame, and tries hard to ensure they realise how beautiful they are.

I look at my little sisters, how smart and confident they are. Its about having positive people around you who lift you up, she explained.

Kourtney would hate for Kendall and Kylie to be self-conscious about their appearances, and truly believes paying them complements will help them grow into rounded, happy, women.

Its a far cry from Kourtneys relationship with Kim, 30, when they were young. The 31-year-old used to refuse to lend her younger sister any of her clothes, resulting in huge arguments.

Kim would steal my jeans and I would go to her school and demand she hand them over! But were so close now, she laughed to more! magazine. (C) Cover Media
