Kelly Clarkson sells out Cobb Energy Performing Arts Centre

Kelly Clarkson originally wanted to become a marine biologist. In seventh grade, one of her teachers overheard her singing in a hallway and asked her to audition for the school choir. In high school, Clarkson performed in musicals such as 'Annie Get Your Gun,' 'Seven Brides for Seven Brothers' and 'Brigadoon.' Robb D. Cohen/ www.robbsphotos.com
