The past two years have been an insane whirlwind of success for Rihanna. In 2004, she was still a teenager who enjoyed participating in beauty pageants and school talent shows in her native Barbados. But a chance encounter with a record producer who was vacationing in her homeland turned her life around overnight. He helped Rihanna record a demo that caught Jay-Z's attention, and before the young singer knew it, she had a record deal with Def Jam. Since 2005, she has pumped out two albums and a slew of chart-topping hits, including "Pon De Replay," "SOS (Rescue Me)" and "Unfaithful."
