The 61-year-old supermodel lets fans in on her family holiday vacation.

— -- Christie Brinkley spent her Christmas holiday in Turks and Caicos with family and she seems to be having a very good time.

The 61-year-old supermodel trekked to the tropical island along with her son, Jack Brinkley-Cook, 20; daughter Alexa Ray Joel, 29; and, Joel's boyfriend Ryan Gleason. And she's letting fans in on all of the fun through her Instagram feed.

The foursome have been doing lots of fun things in the water, including swimming with dolphins.

"I swam with the most famous Turks and Caicos resident today! Jo Jo the friendly dolphin live[s] in the open sea but he LOVES everyone!" Brinkley wrote in one caption.

Brinkley and company even went paddle-boarding.

"Jack and I took our new paddle boards for a spin," she said, "from our vantage point we saw so much beauty!"

The family also got competitive during what Brinkley calls an "annual soccer game." Still, once the game began, the model said she wished one celebrity friend was there. "@justinbieber we all miss your soccer skills this year!" she added.
