The 29-year-old singer co-wrote the song “‘Til It Happens To You” with Diane Warren for the 2015 documentary film, The Hunting Ground, which focuses on rape on college campuses.

“This nomination lends a voice to victims and survivors all over the world,” Gaga tweeted in reaction to her first-ever Oscar nom. “Thank you to THE ACADEMY for recognizing the movement of people who have come together for this film & song in the name of sexual assault.”
