Proud Kim Kardashian cheers on little sister Kylie Jenner from the front row during her catwalk debut ~ star world news

If Kylie Jenner was nervous about her catwalk debut at New York Fashion Week, she didn't let it show.
The 14-year-old half-sister of Kim, Kourtney, Khloe and Rob Kardashian strutted down the Abbey Dawn runway today looking poised and confident.
Her black mini-dress with a tulle, ballerina-like overlay was pure pop-punk princess; it seemed like something Avril Lavigne might wear.

The clapping Kardashians: they support one another as a family

This makes sense, given that the 26-year-old Sk8r Boi singer actually designed the collection, which was presented at Style 360 in New York City Monday.

How did the youngest Kardashian sister land the gig? It helps that Lavigne is dating her half-brother, Brody Jenner.
Aside from favouring a model that's related to her boyfriend, Kylie actually is the perfect girl for the job.

Get it, girl: Kim, 30, makes a crazy face while cheering on her younger sis

Lavigne's line, which is designed exclusively for Kohl's, is predominantly for younger girls; it featured prominently in the singer's 2011 What The Hell music video.
She walked down the runway to cheers and screams from siblings Kendall, Kourtney, Brody and Kim, as well as the newlywed's husband, Kris Humphries, like a pro.
She didn't seem nervous before the job, either.

Nervous: Kylie was spotted in New York ahead of the show today with sister Kendall

The young model was dressed down in a simple grey T-shirt, black jeggings and lace-up boots as she popped back to her big sisters Kim and Kourtney's hotel to prepare.
She also wore a big grin on her face, perhaps because she had just paid a visit to Dylan Lauren's candy boutique, Dylan's Candy Bar.
Although candy and confidence clearly go hand-in-hand, her self-assurance might have come from the support of her family, who took to Twitter to wish her luck.

Brody, 28, posted, 'Gonna need to get a Nap in before this evenings festivities.. Gonna be awesome watching my little sis @KylieJenner walk the carpet!!' He also tweeted at sister Kim, '@KimKardashian gonna be good times.. She is gonna kill it!!' after she wrote, 'Can't wait for @KylieJenner to walk in @AvrilLavigne 's fashion show tonight!'
Avril, who performed in Milan Italy, last night, flew into New York for six hours to attend the show before heading back to Europe for a concert in Amsterdam.

Renee Zellweger was also present to pay homage to her favourite designer, Carolina Herrerra.
