Christie Brinkley first graced the cover of Sports Illustrated in 1979 and over 30 years later, with her turning 60 in February, many would say she certainly doesn't look her age.

Over Labor Day weekend on Sunday, the star attended the 38th Annual Hampton Classic Horse Show in New York and stunned in a weave white dress, brown suede ankle boots and a straw fedora.

The former supermodel believes that her age is nothing but a number.

"My age has so little to do with my image of myself because at a certain point, the number just didn't fit how I felt," she told Shape magazine in July. "It has become irrelevant to me. I just don't feel like that number is representative of my spirit, of my energy or my anything."

Brinkley, a vegetarian since the age of 12, also focuses on eating as healthy as possible. She spoke to the magazine about her diet in 2011, saying that for years her motto has been to "go for as many colors as possible in a day."

"That's my main concept for making sure my kids get all the nutrients-making sure they get the deep greens, yellows and reds and purples, all of that," she said.

The star also works out every day for at least 15 minutes and attempts to include at least 100 push-ups in her daily routine. She told the publication that she enjoys kayaking, paddle boarding, rafting, surfing and swimming.
