Camila Cabello was living her best life on her tropical vacation in the Dominican Republic. On Monday, the 24-year-old singer shared some sexy pictures of herself posing in a black bikini on a boat during the sunset. "I posted no pics because I was hashtag living life, but I was in the REPÚBLICA DOMINICANA BABYYYYYY," she captioned. The "Havana" singer's new pics comes days after she surprised fans by reuniting with her ex-Shawn Mendes in Miami, Fla. The former couple was spotted walking their dog, Tarzan, at a park on Jan. 6. Their reunion comes two months after the pair called it quits.
