The Ramirez brothers spend 12 hours a day at the National School of Ballet, housed in a graceful building that occupies a full half-block in colonial Old Havana.

The triplets say they fell in love with dance in 2007 when their mother took them to see a performance of "The Nutcracker," which is put on every Christmas season and costs just pennies to attend.

In this April 3, 2013 photo, identical triplets, from center left, Marcos, Cesar and Angel Ramirez Castellanos prepare for their ballet class at the National School of Ballet in Havana, Cuba. The 13-year-olds have already separated themselves from their peers technically and artistically, and all three have the talent to make a big splash in the ballet world when they grow up. If they succeed, they will join a long line of celebrated dancers trained in Cuba, where fans from every social stratum follow the careers of ballet stars like Carlos Acosta and Rolando Sarabia as closely as those of baseball players or boxers.

While some identical siblings find it difficult to carve out their own identities, the Ramirezes say they love it. "For me it's a real stroke of luck being a triplet, being able to count on my brothers," said Cesar. "The disadvantage is that sometimes they scold you or correct you for something that another one did." (AP Photo/Ramon Espinosa) (credit:AP)
