Cindy Crawford Celebrates Her 50th Birthday in a Bikini
Cindy Crawford has made many headlines through the years for her incredible bod -- and for good reason.

The supermodel is turning 50 tomorrow, and she flaunted her ageless physique on the beach in St. Barts while vacationing with her husband, Rande Gerber.

@RandeGerber whisking me away for my birthday weekend! ✈️🌴

Crawford also shared a throwback snap on Instagram blowing out candles on her 18th birthday. She really hasn't aged a day!

#TBT My 21st birthday. The cake says "What's Next?" β€” now I know!
