Rachel Bilson is taking her love for stylish shades to the next level: she's signed on as Sunglass Hut's new style adviser. She'll star in ad campaigns, make personal appearances and have her own blog on their Web site, where she'll chat with customers and interview industry mavens like Tory Burch. "I am a huge sunglasses addict. I don't leave the house without [a pair]," Bilson told WWD. " I love talking about fashion, so I can't wait to talk to professionals who share the same passion." She admits that her dream interview is Karl Lagerfeld. "He's an icon and he wears sunglasses at all times!"
