After a stressful day in court, Katy Perry headed to West Hollywood hotspot Craig's to blow off some steam! The singer testified in a copyright infringement lawsuit against her and music producer/collaborator Dr. Luke for their hit single "Dark Horse."

A Christian singer Flame, claims Perry and Luke sampled his 2008 single "Joyful Noise." The singer claims because of Perry's Christian upbringing -- her father being a minister -- she was more likely to have listed to his type of music back in the day and was arguably aware of the song by the Grammy-nominated singer.


Katy's defense team claims she'd never heard it and would have had no reason to -- Katy herself stated on the stand yesterday that she mostly listened to "secular music." She also defended the omission of the allegedly infringed portion of the song in her 2015 Super Bowl halftime performance, saying she had only 12 minutes to perform and wanted to get in as many songs as possible so the intro (the contested beats) was dropped ... even though that performance happened just months after Flame's suit was filed.

Perry also outlined, in detail, the creative process between her and Dr. Luke and explained that "YouTubing" during studio sessions -- a self-described practice she has mentioned in interviews -- is simply searching for cute cat videos by not searching the video sharing platform for beats to lift.

On a more light-hearted note, a funny thing happened in the courtroom -- as one of the attorneys attempted to play "Dark Horse" over the courtroom speakers, there were technical glitches and Katy offered to perform the single live :) Unfortunately for attendees, the speaker system ended up working and Katy didn't sing live. Bummer!
