CARACAS (AFP) - Canadian teen pop star Justin Bieber performed before thousands of screaming teenagers in Venezuela late Wednesday as he concluded a Latin America tour. Bieber, clad in a purple and white jumpsuit, opened his first-ever concert here with "Love Me," as fans packed the Simon Bolivar University football stadium, where the stage had been set up. The 17-year-old teen idol's "My World Tour" has taken him to Lima, Buenos Aires and Rio de Janeiro. The pop sensation soared to stardom after videos of his performances were posted on YouTube, with his album "My World 2.0" hitting the top of the US charts in 2010. His music video "Baby" is one of the most-watched clips ever posted on YouTube, with more than 640 million viewers.
