Rihanna was spotted arriving in Rio de Janeiro, Brazil at the Galeao Airport this past Friday, and the Barbados beauty was looking more than alright! The sexy singer had on a black tank top that gave a generous view of her super toned stomach, and was also dressed for comfort with some shorts and a a black windbreaker track jacket. Fans all know that Rihanna is a BIG World Cup enthusiast, but they're also wondering if Rihanna is there for something else. Perhaps she's performing at the closing ceremony of the soccer games?
