Christie Brinkley poses for Sports Illustrated swimsuit issue with her daughters — at 63!

Christie Brinkley once made Sports Illustrated swimsuit history by appearing on the cover for three consecutive years — in 1979, 1980 and 1981.

But make no mistake! Her days in the pages of SI aren't history. At 63, the supermodel-and-more is returning to the annual issue, and she's not alone.

Brinkley brought two other beauties to pose alongside her in the pages of the 2017 issue — daughters Alexa Ray Joel, 31, and Sailor Brinkley Cook, 18.

“My first thought was, ‘At my age? No way!'” Brinkley told People magazine about the shoot. "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!'”
