Christie Brinkley, 61, Shows Off Her Incredibly Toned Bikini Body on Family Vacation

Those ageless abs! A bikini-clad Christie Brinkley posted a new photo of herself to Instagram on Sunday, December 27, in which the carefree 61-year-old mom of three shows off her incredible physique and toned abs while on vacation with her gorgeous family.

"Hat ✔️rash guard ✔️Recapture360 ✔️ Smile✔️" the world-famous supermodel wrote alongside a snap of herself lounging on a surfboard in the sand. "Get ready for the New Year! ✔️."

In the photo, Brinkley wears a colorful cropped rash guard by NYC-based designer Mara Hoffman and blue string bikini bottoms. The star's lean legs are on display as well as her taut tummy, which looks slimmer than ever as the model leans back for the semi-candid snap.

Brinkley, who was discovered by a photographer in 1973, spilled her age-defying beauty secrets to Us Weekly in an exclusive interview last month, and shared exactly how she maintains that smooth complexion and fit body.

The vegan superstar told Us that she avoids collagen breakdown by snacking smartly. She eats an apple a day, consuming the fruit 20 minutes before meals, and opts for snacks such as frozen blueberries blended to "taste like you're indulging in ice cream."

Brinkley added that she takes extra good care of her skin, exfoliating constantly and using a lactic acid–filled cleanser each morning. "It's something I've done for 40 years," she told Us.

On Instagram, the gorgeous star also posted a "Timeless Beauty Tip” on Saturday, December 26, for her beach-bound fans. 

"When doing sports . . . on the water it's crucial to stop aging by protecting your skin," she captioned a snap of herself paddleboarding in a tropical heaven. "I start by moisturizing my face neck and chest with my own anti aging SPF And IR Defense Sunblock called Recapture 360.. Allow to sink in .. Then I like Neutrogena's range of spray on sunblocks for body..then I use a foundation with SPF 30 or higher on my face to add yet another layer of protection to my face. Look for rash guards that come treated for further sun protection and never forget your hat! This one ties to stay on even in the strongest wind!"

The star also posted photos on Saturday of herself swimming underwater with a dolphin. "I like to hang out with really intelligent beings on porpoise," she wrote. "Jojo is actually a dolphin, not a porpoise, and a famous and friendly one at that! ) #timelessbeauty @brinkleybeauty don't forget to reapply sunblock after swimming!"
