Philadelphia-born Joan Larkin got her start in the band the Runaways (with Lita Ford) when she was just 15 years old. But it was her solo career, which she launched with 1980's 'Bad Reputation' album, that made her a star. 1981's surprise hit 'I Love Rock-N-Roll' was a No. 1 hit single; the album reached No. 2. With her band the Blackhearts, Jett released a string of albums over the years. In 1987, she starred in the movie 'Light of Day' with Michael J. Fox. Jett was inducted into the Rock and Roll Hall of Fame in 2015.
