Christie Brinkley is proving, once again, that age is nothing but a number.
The 59-year-old blond beauty was all smiles while attending the 38th Annual Hampton Classic Horse Show in Bridgehampton, N.Y., over the weekend.
And why shouldn't she be grinning?
Decked out in a white dress paired with suede boots and a straw hat, Brinkley no doubt looked just as good—if not better—than many gals far younger.
Of course, this news doesn't come as a complete shock.
Back in June, Brinkley showed off her fit figure in a sexy swimsuit spread in Haute Living New York.
And just last month, she shared some Instagram photos taken during a recent family vacation in which her beautiful bod could been seen in blue shorts and a bikini top.
