Rihanna hasn't performed by herself onstage since February, when Chris Brown attacked her in his car after a Grammy party. Now the "Russian Roulette" singer is set to make a triumphant return when she performs at the American Music Awards. Rihanna is clearly an American Music Awards favorite and has won three awards in the past. Her mentor, Jay-Z, will also be performing, along with Alicia Keys, Jennifer Lopez and the Black Eyed Peas at the awards show on November 22.
