In this photo taken Saturday, Feb. 2, 2013, samba dancer Diana Prado, right, warms up for a carnival parade at central station in Rio de Janeiro, Brazil. A call center supervisor by day the 27-year-old's double life is split down the middle between the glitz and glam, feathers and body paint of Carnival and the workaday office reality of head-sets and cubicles. Rio de Janeiro samba school dancers are the star attractions of the world's most iconic Carnival celebrations. But they're not on the payroll of the samba groups they represent - and many have to work decidedly unglamorous jobs, serving as maids or secretaries to make ends meet.
