(Cover) - EN Showbiz - Kylie Jenner's sisters helped her prepare for her Fashion Week debut yesterday.

The model-and-reality-TV-personality is famed for appearing on hit show Keeping Up With The Kardashians alongside half-sisters Kim, Kourtney and Khlo Kardashian and the rest of their family.

Kylie made her runway debut yesterday at the Abbey Dawn by Avril Lavigne show at New York Fashion Week. The 14-year-old star says her famous sisters were on hand to provide their support and advice.

"They all showed me and were kind of like 'This is how I would do it'," she told E! Online. "They all said this is supposed to be fun and just get out there. They were all screaming [for me] and it was really fun."

Kylie was nervous before her catwalk debut. The pretty brunette isn't used to being in the limelight, and the fashion show was a big learning curve for her.

"I was a little nervous. I'd never done anything like this before. It really took me out of my comfort zone in a good way," she revealed.

Kylie is also a full-time high-school student on top of her other endeavours. She is used to juggling a hectic work and personal schedule.

"I always have to catch up," she admitted. "But my teachers understand and they send me work and email me. I get through it!"

The star looked stunning in a black mini dress with a tulle overlay at the show on Monday.

Kylie's siblings, Kim, Kourtney and Kendall all cheered her on from the front row of the fashion show, along with half-brother-and boyfriend-of-Avril Brody Jenner and Kim's husband, Kris Humphries. (C) Cover Media
