Lady Gaga delivered an extremely powerful performance at the 88th Annual Academy Awards on Sunday.
After being introduced by Vice President Joe Biden, Lady Gaga took the stage at the Oscars 2016 to perform "Til It Happens To You."
The Oscar-nominated song, co-written by Lady Gaga and Diane Warren, is featured in the The Hunting Ground, a documentary about sexual assaults that occur on college campuses.
Lady Gaga, a sexual assault survivor, had other rape survivors onstage with her during her performance, making it even more powerful. Each of the survivors had messages like "unbreakable" and "it happened to me" written on their arms.
At the end of the performance, Lady Gaga stood beside and held hands with the survivors. The performance received a standing ovation from the audience and left Rachel McAdams and Kate Winslet in tears.
When Vice President Biden introduced the performance he encouraged everyone to sign the ItsOnUs.org pledge.
"A pledge that says, 'I will intervene in situations where consent has not or cannot be given,'" he explained.

Before the show on Sunday, Lady Gaga sent Kesha a very special tweet.
".@kesharose I'll be thinking of u 2nite. This is not over we'll stand by u until you are free to live a HAPPY life. Everyone deserves that." Lady Gaga tweeted.
Kesha's been going through a very tough time in her ongoing legal battle against Dr. Luke, who Kesha alleges sexually assaulted her. Lady Gaga recently met up with Kesha to show her support. The two posed for a picture together and Lady Gaga captioned it, "Free Kesha."
Just minutes before taking the stage, Lady Gaga posted a photo on Instagram of her and fiancé Taylor Kinney kissing.
She captioned the post, "I never thought anyone would ever love me because I felt like my body was ruined by my abuser. But he loves the survivor in me. He's stood by me all night proud and unashamedly. THATS a real man. ❤️"
