Before Katy Perry was a pop superstar, she was a Christian music singer who dropped out of high school at 15 to pursue her dream. Despite her success -- three studio albums, with her fourth expected in 2016 -- she regrets dropping out and later got her GED.
The once emerging country singer was an underdog in a genre that was male-dominated. Her sound and songs were unconventional. Her look pushed back against the big hair and heavy make-up of the musical Dixie queens before her. She was a girl with a guitar and big heart.
