Kylie Jenner’s runway debut

Kylie Jenner’s runway debut, All the Kardashians cheered Kylie on! Kim’s hubby Kris Humphries threw her a high five and Brody Jenner’s girlfriend Avril Lavigne told us exclusively: ‘She’s adorable!’

Kylie Jenner‘s aspirations of becoming a model have become a reality as she looked stunning on the catwalk during New York Fashion Week at Style360 and Avril Lavigne‘s Abbey Dawn show on Sept. 12! Cheering her on in the front row was much of her super-supportive family, including half-sisters Kim Kardashian, Kourtney Kardashian, Kim’s hubby Kris Humphries, Kylie’s sister Kendall Jenner and half-brother Brody Jenner. Kylie, 14, had a practice run with the other models before attempting the real runway. Her sister Kendall cheered her on from the sidelines during practice.

When everyone was seated for the actual show, the Kardashian caravan arrived. A flash mob rushed Kim, Kourtney and Kris — but security finally got everyone to sit down and escorted the reality stars to their seats.

As the runway started, the sisters went crazy in anticipation of Kylie coming out. And once Kyle hit the stage, the whole group went wild. Kendall took pictures of Kylie with her camera. The Kardashians were all smiles and super happy to see Kylie do so well.

In a total of three outfits, Kylie closed the show in an black ballerina dress. As she walked back for the final model lineup, Kris threw up a high five as she strutted by.

She’s a natural beauty, but we’re sure Kylie got her foot in the door through nepotism — after all, the collection was started by her half-brother Brody‘s girlfriend Avril.

“She did a really good job,” Avril gushed to HollywoodLife.com of Kylie’s performance. “I think she’s adorable. She’s the youngest of all the sisters and I love her edge, so she’s perfect to walk in the Abbey Dawn [show].”

And the fact that Kylie’s only 14 didn’t seem to matter to Avril. “She’s beautiful so I was really happy to have her,” she said.

Avril was also quite excited to see her line on the runway. “It was exciting,” she explained. “It was a massive honor to be in New York for Fashion Week. It’s my second time being in New York and having a show. It’s cool. I try and make it like a rock show as much as possible. They are all my up tempo songs and make if casual and comfortable, not uptight. I would never want a fashion show to be uptight of mine.”
