Lady Gaga Loses the Oscar but Wins the Audience With Moving Performance

Gaga gave a dramatic performance of her nominated song "Til It Happens To You."

Gaga then appeared alone on stage, seated behind a white piano.

Singing powerfully the words, "til it happens to you, you don't know how it feels," she was joined by a dozens of abuse survivors. After standing in the shadows, they joined her on stage at the song's climax. On each of their forearms was written different words, including "unbreakable" and "survivor." Together they joined hands with the singer as the audience rose to their feet, clearly moved by Gaga's performance.

Earlier on the red carpet, Gaga told ABC News' Robin Roberts why the song was "such an important song to me."

"One in five women will be raped before the time they finish college," she said. "It's something that is deeply connected to my heart. I myself am a survivor."

The Grammy-winning singer told Roberts that she was "very grateful to the Academy for giving us this world stage to reward survivors for being brave and coming forward."
