Nominated for three 2013 Grammy categories, the Barbados beauty's first Grammy appearance was in 2007. Her first win came year later when she was awarded a trophy for Best Rap/Sung Collaboration for "Umbrella." Rihanna holds the current Grammy record for the female artist with the most wins (three) in that category.
