It’s hard to believe Christie Brinkley is 60-years-old today, especially when she looks the way that she does! The supermodel and mother of three—Alexa Ray Joel, 28, Jack, 18, and Sailor Brinkley-Cook, 15—is proving that age is just a number and yes, you do get better with age. The original “Uptown Girl” and former Broadway star—how could we forget her Roxie Hart days—is dipping her toes back in the modeling pool thanks to her new deal with IMG Models, where she signed on with her daughter Sailor. As for her side projects, Brinkley is showing no signs of slowing down given her line of Hair2Wear extensions and skin care collection, CBBeauty, launching soon. Not bad for 60!

To celebrate Brinkley’s sixth decade, look at some of our favorite supermodels from then to now in our gallery!
