More pics from the show

Avril Lavigne may not officially be part of the family.

But her connection to the Kardashians - she is dating the sisters' stepbrother, Brody Jenner - meant the whole clan turned up in full force to her runway show.

Kourtney, Kendall, Kim and her new husband Kris Humphries all sat front row, the girls looking ultra glossy.

But they weren't only showing support for the designer, who was unveiling the latest collection of her streetwear line, Abbey Dawn.

The baby of the bunch Kylie, who has her eye on a modelling career, was making her runway debut in the show.

The 14-year-old strutted out in several looks, including  a bouncy black ballerina dress to cheers from her family.
