Katy Perry Has A Tear-Jerking Performance At The 57th Annual Grammy Awards!

Katy Perry gave a tear-jerking performance Sunday night at the Grammy Awards.

The singer belted out one of her most moving songs, "By the Grace of God," after a woman spoke onstage about her experiences with domestic violence.

President Obama also had a video explaining the importance of speaking out against violence against women.

Though she wore a sparkly gown on the red carpet, Katy went for a more subdued look onstage as she sang her song, which encourages people to find happiness and not give up hope.
