Katy Perry Arrives in Court for Copyright Lawsuit

(TMZ) Katy Perry just arrived to an L.A. Federal Courthouse where a trial is set to take place involving her song “Dark Horse.”

Perry — wearing a mint-colored suit — is expected to testify in the trial today in what has been a lengthy legal battle.

As TMZ previously reported … Katy was sued by Christian rapper Flame back in July 2014 after claiming Katy’s 2013 hit track “Dark Horse” is a total rip-off of his Grammy-nominated gospel track “Joyful Noise.” Flame’s music label uploaded the music video in 2008 to YouTube and it has nearly 4 million views.

According to the suit … Flame says Perry not only jacked their religious music … she also destroyed his reputation in the Christian music world because they’re now associated with the anti-Christian witchcraft and imagery that appears in the “Dark Horse” music video.

Flame claims Katy jacked the underlying beat … but she’s calling BS, saying there are no significant similarities.
