It's been 36 years since Christie Brinkley was on the cover of the Sports Illustrated Swimsuit Issue -- but she's back. The 63-year-old former supermodel still looks amazing, but the best part of her return to bikini-clad photo-taking is that she got to do it with her two daughters, Alexa Ray Joel, 31, and Sailor Brinkley Cook, 18. Let's just say that both girls were gifted with some pretty fantastic genes.

"My first thought was, At my age? No way!" Brinkley said in an interview with People magazine. "When I turned 30, I was like, 'This is the last time I’m posing in a bathing suit!' When this issue comes out, I’ll be 63. I thought, 'Those days are over.' But to get to do it with my girls, I thought, One last go!"
