Shakira appeared last Saturday in Cartagena, Colombia, at the center of the platform of the VI Summit of the Americas', with all the formality required for its opening, to give her own rendition of Colombia's National Anthem in front of the leaders of the Americas.

However, her performance was not as perfect and successful as usual, since the singer changed some words and critics over Twitter and Facebook didn't wait to attack, especially Colombians, who wondered if Shakira had already forgotten the anthem.
