Eyewear ambassador Rachel Bilson

Rachel Bilson has been named the first eyewear ambassador for Sunglass Hut.

The stunning actress has long been a fan of shades - pictured wearing everything from wayfarers to aviators - which has led to her appointment as the eyewear brand's style director.

She told WWD: "I was very flattered when Sunglass Hut approached me to do this. I can't say what makes me a good style adviser for them, but I am a huge sunglasses addict. I don't leave the house without a pair."

Rachel will front the company's advertising campaigns and also write a trend blog for the company as well as hosting online chats and video podcasts with people in the fashion industry.

Fabio d'Angelantonio, CEO of Sunglass Hut, explained his reasons for choosing Rachel.

He said: "We wanted a symbol of our philosophy, somebody who's familiar and relevant to our target consumer, but at the same time was herself sunglasses obsessed."

Rachel's first interview will be with designer Tory Burch, and she is also hoping to meet Karl Lagerfeld at some point in the future, as he is another huge fan of shades.

Of Karl, Rachel noted: "He's an icon and he wears sunglasses at all times."
