Shakira, Ricky Martin, and dozens of other Spanish-speaking pop stars performed at simultaneous fundraising concerts in Mexico City and Buenos Aires yesterday, reports the LA Times. “It is doable, we can really eradicate poverty,” said the Colombian singer, whose shows benefited Alas, a charity that helps Latin America's neediest children. Shakira secured nearly $200 million in donations from billionaires Howard Buffet (son of Warren) and Carlos Slim, reports the BBC. (More Shakira stories.)
