Katy Perry is facing a new lawsuit claiming she stole "Dark Horse." The worst part—the supposed misappropriation came from a Christian rapper... and Perry was raised in the church! Her preacher dad ain't gonna be happy. 

The copyright suit in a Michigan federal court comes from hip-hop artist Flame, who penned the 2008 gospel-rap track "Joyful Noise," featuring Lecrae. It appeared on an album that was nominated for a Grammy and allegedly sounds shockingly similar to "Dark Horse."

The case reads, "By any measure, the devoutly religious message of 'Joyful Noise' has been irreparably tarnished by its association with the witchcraft, paganism, black magic, and Illuminati imagery evoked by the same music in 'Dark Horse.' Indeed, the music video of 'Dark Horse' generated widespread accusations of blasphemy and an online petition signed by more than 60,000 demanding removal of an offensive religious image from the video."
