Christie Brinkley Wows In Bikini While On Vacation In Turks And Caicos

Who says 61 ain't fun?!

Christie Brinkley looked all kinds of amazing while vacationing with her family in Turks and Caicos for the holidays. 

In one Instagram photo, the 61-year-old supermodel poses on a surfboard, pairing a Mara Hoffman Supernova Black rash guard with a tiny bikini bottom as she relaxes in the sun. 

In a collage of snaps, Brinkley swims underwater with a dolphin, rocking a blue two-piece. 

She has been open and honest about her beauty routine, saying sunblock is key, as is eating well and staying active. 

"At 61, I learned the second you sit still, you rust. You have to keep moving. That's very important," Brinkley said on AOL Build last month. "Even at 61, you can get back into shape ... Your body is amazing, if you give it what it needs, it will respond. It's never too late to get back into shape." 

Brinkley has been enjoying some downtime in paradise with her children -- son Jack Brinkley-Cook, 20, and daughter Alexa Ray Joel, 29, who brought along her boyfriend Ryan Gleason.
