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.
