Cue the waterworks!

Lady Gaga took the stage at the 2016 Oscars tonight to perform her song "Til It Happens to You" from the documentary The Hunting Ground, which is about sexual assault on college campuses. The 29-year-old, who has previously spoken out about being raped when she was a teenager, left the entire crowd in tears after emotionally and powerfully singing lyrics like, "Till it happens to you, you don't know how it feels."
