WATCH: Kesha sings "Till It Happens To You" by Lady Gaga.

Kesha, who is in the middle of a legal battle against her music producer and alleged rapist Dr. Luke, stepped out at The Humane Society of the United States Los Angeles Gala on Saturday night where she delivered a powerful rendition of Lady Gaga's latest single "Til It Happens to You."

 

Joined by Diane Warren onstage, Kesha got emotional before performing the song. "I want to dedicate this song to every man, woman, child, and animal that has ever been abused", she said. During the performance, photos and video of caged farm animals played on a big screen at the back of the stage.

 

"Till It Happens To You" is a Grammy and Oscar nominated song written by Lady Gaga and Diane Warren. It is an official soundtrack for "The Hunting Ground", a 2015 documentary film about sexual assaults that occur on college campuses.
