Lady Gaga held nothing back at Sunday night's 88th Academy Awards. The singer's emotional performance of "Til It Happens To You," an Oscar-nominated song she co-wrote with Diane Warren for the documentary The Hunting Ground, included 50 sexual assault survivors standing alongside Gaga (a survivor herself!) in solidarity.

Vice President Joe Biden introduced Lady Gaga's performance with a powerful request: "I'm asking you to join millions of Americans, including me, President Obama, the thousands of students I’ve met on college campuses, and the artists here tonight to take a pledge. A pledge that says, 'I will intervene in situations where consent has not or cannot be given.' Let’s change the culture."

Following the awards show, Kesha tweeted her thanks to Lady Gaga and Biden.

Like many celebrities, Lady Gaga has publicity voiced her support of Kesha. The Warrior singer is stuck in an ongoing legal battle against her alleged rapist, producer Lukasz "Dr. Luke" Gottwald, and Sony Music. The judge recently sided with Gottwald and Sony, which is a sobering reminder that we need to be talking about sexual violence and rape culture now more than ever.

Thank you for standing next to me on stage. Thank you for all the things you said, for listening to my story and sharing yours. I will never forget it. 50 survivors, so brave, relentless determination.
