Kim Kardashian's little sister Kylie Jenner showed off her modeling credentials when she opened and closed Avril Lavigne's Abbey Dawn New York Fashion Week show on Monday night (10Sep12).
The big launch marked the pop punk's first public appearance since announcing her engagement to Nickelback frontman Chad Kroeger.
Lavigne told Billboard.com her new Abbey Dawn line was inspired by musicians "Joan Jett, David Bowie and the Sex Pistols, to name a few".
And she was delighted when 15-year-old Jenner agreed to be part of her big New York fashion show, and tweeted after the launch, "Thank you to Kylie Jenner and all the beautiful models who rocked the Abbey Dawn runway tonight!! Kick a**."
