Christie Brinkley, 59, Sizzles in Swimsuit Pic

Former supermodel Christie Brinkley proved she’s still one hot mama -- posing in a swimsuit for Social Life magazine’s May 2013 edition. Check out the pic!

The 59-year-old graced the cover of the Sports Illustrated Swimsuit Issue three times between 1979 and 1981 (check out her old covers here), but this marks her first bathing suit photo in more than 30 years.

Brinkley, a mother of three, invited the mag to her home in the Hamptons for the sexy shoot, and admitted she’s “addicted” to Instagram.

She explained, "I find when I walk with a camera in my hand, I am extra alert and attuned to all the extraordinary beauty that abounds, from the smallest detail of a powdery pistil in a flower to the texture of the sky and the clouds that mesmerize me. Taking pictures intensifies my appreciation and awe!”
