Katy Perry, her co-writers and her record label have been ordered to pay $2.78m (£2.3m) to a rapper after a jury found her hit single ‘Dark Horse’ was copied from a Christian song.
The singer herself must pay $550,000 (£453,000), with Capitol Records picking up the majority of the bill.
It comes after relatively unknown artist Marcus Gray, known as Flame, and two co-authors, won a five-year law suit against the pop star and her team.
They claimed Perry’s 2013 track stole from their 2009 Christian rap song, Joyful Noise.
Although the payout was less than the $20m (£16.5m) their lawyers sought on their behalf, they said they were pleased with the decision.
Gray’s lawyer Michael A Kahn told the jury: “These defendants have made millions and millions of dollars from their infringement of the plaintiff’s copyright.”
Because the rhythmic instrumental riff from Joyful Noise plays through 45% of Dark Horse, Mr Kahn said his clients were entitled to 45% of the entire earnings of Perry’s album Prism, where her song appears.
