Revelation of the Day: Katy Perry Was Once The Backup Vocalist For P.O.D.

Before Katy Perry danced with a Left Shark and kissed a girl (and liked it), she was a backup vocalist for Christian alternative rock band P.O.D.

This little-known fact was rediscovered today by Metal Sucks, and we can't stop laughing about it.

Perry was known as Katy Hudson when she provided vocals in 2006 for "Goodbye Now." She's featured in this music video starting at 3:36.

And she joined the band on The Tonight Show around the 3:24 mark.

Katy sure has come a long way.
