The young actress will serve as a brand ambassador for the fashion house and its subsidiary jeans line and she'll also front the company's 2012 ad campaigns.

She says, ""I've always loved Donna Karan's creations. To be a part of the brand's message is incredibly exciting because it feels like such an organic fit. It's easy to talk about how these clothes work for my lifestyle, whether I'm in New York, L.A. or traveling for work.""
