Supermodel and businesswoman Christie Brinkley traveled to the white sand beaches of Turks and Caicos for a family vacation. She shared photos of the trip on Instagram. "Sunset bike and stroll ?," Brinkley captioned the photo. "P.S. if you don’t ride the bike it will rust. Same thing with your body! You’ve got to move it! Move it! ? ??????" Brinkley is known for how seriously she takes her health, and movement is one of the reasons she looks so good at 67. She is featured in a new Sports Illustrated Swimsuit Issue. Brinkley posted side-by-side photos of herself posing for the magazine in the '70s to a photo of her posing for this year's issue. She applauded the magazine for its' "all-encompassing inclusiveness and support for every woman." "I worked with @siswim from the 1970s till I’m ALMOST 70…," Brinkley captioned the post. "I appreciate and applaud their ever-expanding embrace of women, showing the world that when a woman feels beautiful she IS BEAUTIFUL!" GET DEALS ON TURKS & CAICOS HOTELS HERE!
