"I played a woman with cancer in Sweet November. I went down to a size 6 and I felt completely uncomfortable. I remember being cold and wrapping my arms around my body and feeling ribs and bone. I felt totally unsexy," she says in this month's issue of British Elle.

The actress also sounds off about why she'll never marry long-term boyfriend Stuart Townsend. "I want to know that I wake up every morning because I want to, not because a pieces of paper says so."
