Fat Tuesday celebrations around the world

In this photo taken Saturday, Feb. 2, 2013, samba dancer Diana Prado performs during a carnival parade at central station in Rio de Janeiro, Brazil. Prado spends her daylight hours working as a supervisor at a call center. At night, she is a samba dancer, or "passista," as they're known in Portuguese. Prado made her Carnival debut at age 19, after auditioning for a spot with the Sao Clemente, one of 13 top-tier schools that will compete for the annual titles at the Sambadrome this weekend.
