Instagram The seasons may change, but Christie Brinkley's body continues to stay amazing.
While some parts of the country are experiencing freezing temperatures—we're looking at you Chicago residents—the 61-year-old model was able to travel to a tropical destination where bikinis were more than appropriate.
Joined by her children Sailor Brinkley-Cook and Jack Brinkley-Cook, Christie and her beautiful family were able to soak up the sun and enjoy the gorgeous weather on private boats.
"Snorkle Trip. We saw 4 tortoises, sea fans in purple and yellow, puffer fish, Dory and Nemo fish, schools of colorful fish, and some huge barracudas…One of whom chased Jack and me while snapping his Sharp jaw at us!" Christie wrote on Instagram. "Great undersea adventure!"
While the vacation may sound fun and relaxing, many fans want to know more about how Christie stays in such great shape at her age. As it turns out, the former Sports Illustrated model has a few products up her sleeves that anyone can use.
"I am wearing Neutrogens Wet Skin broad spectrum. And I always have a hat!!" she wrote on Instagram while posing in a purple bikini. "I used my skin quenching Recapture Day Cream +IRDefense. Then on top, I put SmashboxCamera Ready Broad spectrum SPF 35 color Medium and Hourglass Radiant Bronze Light just to add a sunny glow."
Christie assures fans that you can find more tips in her best-selling book Timeless Beauty available now.
Although the vacation featured lots of R&R, Christie and her family made it a priority to attend a family friend's wedding right along the coast.
While the evening attire called for dresses and flip-flops, followers of the blond beauty were in awe of how similar Christie and her daughter looked at the ceremony.
"Me and my baby, my baby n me, we're bout as lucky as lucky can be," the proud mom wrote on Instagram. "Watching a wedding in the Caribbean Sea. May Beth and Thomas love forever in clear blue skies and stormy weather! @carafayeearl @realrobertearl @sailorbrinkleycook #luckyhouse #parrotcay."
