Katy Perry will perform By the Grace of God at Grammys 2015

Billboard magazine further confirmed Katy Perry’s performance at the upcoming Grammy Awards (2015), but she will not play the hit single "Dark Horse (Feat. Juicy J)."

Despite being given to a category with the song, which includes the album "Prism", the artist chose to sing the ballad "By The Grace Of God" which she wrote in collaboration with Greg Wells after her divorce from Russell Brand.

According to the magazine, the singer is also preparing a dance for the performance, which will be the main focus of the performance. It was unclear if the star will make a mashup with "Dark Horse (Feat. Juicy J)", as she did at the Grammys 2011 with the songs "Not Like The Movies" and "Teenage Dream."

Other performances confirmed for the event are Rihanna, Ed Sheeran, Ariana Grande, Sam Smith, Madonna, AC / DC, Paul McCartney, Kanye West, Tony Bennett & Lady Gaga, Adam Levine, Gwen Stefani, John Legend, Pharrell Williams and more. The event will be broadcast live on CBS at 8/7c.
