Court rules > Katy Perry copied Dark Horse from Christian rapper Flame.
Katy Perry copied her 2013 song Dark Horse from a Christian rap song, a US court has ruled.
Katy gave evidence in the week-long trial, denying she had ever heard the 2009 song Joyful Noise by Flame before recording her track.
She even offered to perform Dark Horse for the court room when her lawyers were unable to play the song for jurors because of a broken speaker system.
But despite the joke, the jury ruled against Katy on Monday.
