By Rodrigo Viga Gaier RIO DE JANEIRO, May 3 (Reuters) - Some 2 million people packed Copacabana Beach on Saturday for a free concert by Shakira, Rio de Janeiro city officials said early on Sunday, marking the biggest show of the Colombian pop star's career.

Two million people did not show up on Copacabana Beach just to hear "Hips Don't Lie." They showed up for the whole argument.

An estimated 2 million people attended the show in Rio De Janeiro, where Shakira delivered a nearly 30-song set that included guest appearances by Anitta, Maria Bethania, and Caetano Veloso.
