They must give models special training or something that allows them to look great as they age, because Christie Brinkley, 59, looks as amazing as she did when she first graced the cover of Sports Illustrated in 1979. And then again in 1980. And 1981. (Seriously, SI was obviously in love with this lady for three consecutive years. And who can blame them.)

The Long Island resident performed this weekend at the Guild Hall in the Hamptons. She performed on stage with Ralph Macchio, actress Brooke Shields, actress/poker player Jennifer Tilly and comedian Dick Cavett for “Celebrity Autobiography.”

The end of summer makes most people sad, and being a parent, Brinkley has something else to wish her summer would last a little bit longer. Her son Jack Brinkley Cook is heading off to Emerson College. Brinkley said, “Whenever I stop and think about it I just weep. The back to school routine will be a little relaxing.”

But it wasn’t just a performance on stage that had the former model in the Hamptons for summer activities. Brinkley also attended the 38th Annual Hampton Classic Horse Show – Grand Prix in Bridgehampton, New York on Sunday. Brinkley was turning heads, as usual, with a form fitting white dress, a cowboy-style fedora, a country-inspired belt, and brown suede ankle boots.

One person in the Twitterverse begs the question, is Brinkley the hottest 59 year old ever?

If you need more proof of her beauty, head on over to Daily Mail Online and take a gander for yourself.

Her 15-year-old daughter Sailor Cook also attended the equestrian event.

Most recently, Brinkley had a guest role on Parks and Recreation as Jerry Gergich’s wife Gayle. A surprise for fellow characters and viewers alike.
