Call Benjamin Button -- this supermodel seems to be aging in reverse. In fact, she's gotten more beautiful over the years. Maybe that's why getting older doesn't bother her one bit. "I don't worry about a number. I'm fine with aging," this former supermodel told Harper's Bazaar in 2012. "It's always surprising to get asked to do a job I did 20 years ago. I'm very blessed, and I know that."
