Is Shakira showing her Italian allegiance at this year’s World Cup? It may seem so, as the sultry singer is set to wear a full Roberto Cavalli look for her performance at the opening ceremony of the 2010 FIFA World Cup in Johannesburg on June 10. Anyone who’s a soccer fan will know that Shakira’s new single, “Waka-Waka,” is the official song of the games. For the occasion, she’ll be wearing a black and white zebra-printed jumpsuit, a silk fringed skirt (which detaches) and bracelets with brown leather fringe and gun silver irregular pearls created especially for her by Cavalli.
