Supermodel Cindy Crawford tells Rachael the secret behind her 10-year marriage to restaurateur Rande Gerber. "Marriage is hard work," she admits, "and anyone who thinks it's easy ... unfortunately, all the movies show you this romanticized version of what marriage should look like, and you think, 'If my relationship is not like that there must be something wrong.' But that's not true -- it is hard work, every day. I think Rande and I really work hard at having couple time because family life does tend to overwhelm you and take over."

In addition to successfully juggling family and a career, Cindy has made time to be environmentally conscious. "The thought of going green is intimidating, but what I realize is you can just start with one thing. You know, let's say, unplugging your appliances when you're not using them. Then, make the next step," says Cindy, who is proud of her eco-friendly lifestyle. She is teaming up with PUR to introduce a reusable water bottle, with proceeds going to a charity for children's safe drinking water in underdeveloped countries.
