Cindy Crawford: The 10 Turns 50!

The queen of the supermodels, Cindy Crawford, turns 50 years old on Saturday — not that you could tell from looking at her without makeup and barely dressed. Husband Rande Gerber swept Cindy off to St Barts for an extended birthday celebration in the tropical paradise.

As always, Cindy was impeccably dressed, sporting a skimpy black bikini that hid nothing — not that she has anything to hide! Even without makeup Cindy seemed to shimmer in the sun! And how about those legs! And that flat tummy!

Rande, 53, joined Cindy in splashing about in the surf. The couple have been married for 18 years and share son Presley, 16, and daughter Kaia, 14.

Cindy may be totally comfortable in her skin now, but back in 1993 she was looking over her shoulder, professionally speaking: "I'm 27 now and I'm out there with 18-year-olds!" she told Katie Couric on the “Today” show.

"I feel ... not old in my age, because I feel like I'm just starting my life," Cindy went on to say. “But I feel like my head is in a different place, sometimes, backstage. My life is a lot richer now, and I don't only want to talk about what the latest shade of lipstick is."

More recently, Cindy was asked her thoughts on turning the big 5-0! “As a woman, I don't go, 'Hey, whoopie!'" she admitted. "But I'm grateful for my life. It's just a number, right?"
