Feeling Chilly Today? Just Look at Christie Brinkley's Insanely Hot Bikini Body

Christie Brinkley may be 61 years old, but she is looking better than ever! The actress took to Instagram earlier this week to share stunning photos from a family vacation to Parrot Cay Island in the Turks and Caicos. Christie, who was joined by two of her kids, Sailor and Jack, soaked up the sunshine while snorkeling and relaxing on a boat. "Snorkle Trip," she wrote on Instagram. "We saw four 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. Great undersea adventure!"

While the family clearly enjoyed their time away, they also attended the beachside wedding of a family friend. Christie shared a gorgeous selfie of her and Sailor from the ceremony, looking almost identical with their long, blond hair. "Me and my baby, my baby and me, we're bout as lucky as lucky can be, watching a wedding in the Caribbean Sea," Christie captioned the shot.
