12 Shocking facts about Katy Perry – You never knew this! (With Pictures)

2. She sang backup for a big star

While she was trying to get her foot in the door of the music industry, Katy Perry took on gigs like providing backup vocals on other artist’s songs. For example, she can be heard in the background of P.O.D.’s “Goodbye For Now” (and spotted in the music video for the same song). The biggest name she backed up, however, has to be Mick Jagger himself – she sang backup on his song “Old Habits Die Hard,” which won a Golden Globe for Best Original Song in 2005. Nowadays, any aspiring pop star would kill to sing backup for someone as big as Katy Perry, so things have really come full circle.
