Christie Brinkley Flaunts Sexy Bikini Body at 61

There is so much to be thankful for this holiday season, including Christie Brinkley’s bikini body!

Just a few days before Thanksgiving, Christie took to Instagram to show off her hot body while enjoying a tropical vacation.

Brinkley also posted other bikini snaps with her daughters and wrote, "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!
