Gisele Bündchen slipped into a leopard-print bikini to hang on the beach in Costa Rica yesterday. In addition to her sexy printed two-piece, Gisele wore an oversize sun hat and body harness to carry her baby daughter, Vivian Brady, and played with a friend's dog between dips in the ocean. Gisele is relaxing with family and friends in Central America after a busy couple of months; she spent time in Paris while shooting for Vogue and brought her sons, Jack and Benjamin, to Disneyland for a fun family outing in Anaheim, CA. Gisele's tropical vacation could also be a celebratory one, as she rang in her 33rd birthday earlier this week. She took to Instagram to share cute photos of her big day while exploring the outdoors with Ben and Vivian and also included a sweet tribute to her twin sister, Patricia.
