Demi Lovato pulled out all the stunts for some bikini pics. Lovato, 33, took to Instagram on Tuesday, November 25, to show off her bikini body while escaping the cold and enjoying a tropical getaway. As she soaked up the sun, the singer rocked a black-and-white set. Her two-toned bikini top was equipped with white straps and black cups, as well as a delicate ring connecting the top. Lovato styled the look with coordinating bottoms featuring a high-waisted silhouette with a white heel finished with a ring over her hip and black cheeky bottoms.
