Celebrity Wednesday--Katie Couric

Although not over sixty, Katie Couric has let Yahoo in on some easy tricks to add sparkle to your beauty routine.

She recently stopped by "Daily Shot" to talk beauty secrets with Ali, and she shared an easy tip for keeping pearly whites sparkling. "Take a whitening toothpaste, any brand," Katie says. "Put it across your teeth, and then when you get in the shower, you just keep it there. ... It will do the same thing as whitening strips." The 56-year-old also keeps her skin glowing by always trying to wash her face before going to bed, even though she admits to slipping up every once in a while. "Sometimes I forget, and I rationalize it and say, well, it's good because I'm not drying out my face with water," she said. Katie also stresses the importance of exercising to keep a youthful look. "I try to spin," she says. "You burn a lot of calories, and it's so good for cardiovascular health ... because it does really push you." Another routine? "I try to walk with my friends to socialize instead of going out to lunch."
