64-year-old model, actress, and businesswoman Christie Brinkley achieved worldwide fame in the late 1970s with three consecutive Sports Illustrated Swimsuit Issue covers. She also spent 25 years as the face of Cover Girl—the longest cosmetics contract of any model in history. Over the decades, Americans have consistently named the blue-eyed beauty as one of the most beautiful women of all time.

How is it that Brinkley has managed to hold on to her youthful beauty for decades, still stunning well into her 60s? According to Brinkley, it’s fairly simple: she starts each day with a juice of a different color. She blends together a healthy dose of fruits and vegetables every morning to ensure she gets the nutrition she needs to stay healthy.

She also has a routine of going for a run with her dogs each morning to keep both her and her furry friends fit. Brinkley has said having a positive, grateful mindset in life has helped her stay “young at heart.”
