If there is a fountain of youth, Christie Brinkley has found it and is stubbornly hiding it from the rest of us.
The 64-year-old supermodel/superhuman just dropped a new swimsuit photo shoot, for Social Life Magazine, on Instagram, and it's as if she's been frozen in ice since 1983's National Lampoon's Vacation.
The perennial bombshell inspired similar headlines when she made an appearance at a Sports Illustrated Swimsuit event in Miami, giving much younger models a run for their money.
Sixty and sexier than ever... only Christie Brinkley could make it possible.
