Rihanna

At the age of 15, Rihanna received her big break when one of her friends introduced her to music producer Evan Rogers, who was vacationing in Barbados with his wife. Rogers, along with his partner, Carl Sturken, helped Rihanna record material in the U.S. which was sent to various recording companies. One copy of Rihanna's work was sent to Jay-Z, who eventually signed her to Def Jam Records. Rihanna cites Alicia Keys, Beyoncé Knowles and her Caribbean background as major musical influences.
