In making the announcement Monday, Guerlain described the 31-year-old actress, an Oscar winner for her roles in “Million Dollar Baby” and “Boys Don’t Cry,” as a “radiant and natural beauty” who does not conform to stereotypes.

“Her background of always opting for the more challenging and ‘risky’ roles coupled with her warm and genuine personality, a far cry from the usual Hollywood mold, were all factors that made her an obvious choice for Guerlain,” the luxury French fragrance and beauty company said in a statement…

A spokeswoman for the company declined to comment Monday on the terms of the deal or the details of the fragrance.
