Katy Perry performs ‘By the Grace of God’ to end domestic violence at Grammy Awards 2015 (VIDEO)

Katy Perry performed “By the Grace of God” at the Grammy Awards 2015. This was a powerful performance to raise awareness about domestic violence in America.

Katy Perry just came off a week from headlining the Super Bowl Halftime show with Lenny Kravitz and Missy Elliott. She tones things down a bit with this ballad from her latest album Prism.

Two huge music weeks in a row for Katy Perry. Not bad!

She was also a performer last year when she sang “Dark Horse” with Juicy J (and the dark horse literally upstaging everyone).

The 57th Grammys aired on CBS from the Staples Center in Los Angeles on Sunday, Feb. 8.
