Cindy Crawford

Age: 50

Secret: Cindy recently spoke to Redbook about how she seems to not age. "There's no secret!" she reveals. "Looking good is about eating right, getting enough sleep, and drinking lots of water." She also added, "You have to get moving. I work out several times a week, and I hike and ride bikes. I also eat healthy, but I don't deprive myself. I live by the 80 percent rule: I try to be 80-percent good 80 percent of the time."
