Lady Gaga and Joe Biden have an important message about sexual assault: It's on us (as in, everyone) to prevent it from happening.

In a video shared to both of their social media accounts, the "Million Reasons" singer and former Vice President are teaming up for "It's On Us," an initiative to stop sexual assault. According to the website, It's On Us is "a rallying cry inviting everyone to step up and realize that the solution begins with us."

“We want to make it real clear: it’s on us,” says Biden in the video message. “It’s on everyone to intervene, to stop abuse when they see it and when they hear about it.” He also goes on to laud Lady Gaga for her outspokenness about the issue of sexual assault, a cause that she's championed through both her music and her advocacy.

“I am a sexual assault survivor and I know the effects, the aftermath, the trauma: psychological, physical, mental,” the singer shares in the video. “It can be terrifying waking up every day feeling unsafe in your own body.”

Gaga sings about her own experience with sexual assault in "'Til It Happens To You," a song she penned for The Hunting Ground, a film about the rape culture on college campuses. At the 2016 Academy Awards, she was introduced by Biden, who spoke powerfully about how we as a society need to change the way we handle sexual assault. Gaga then famously invited other sexual assault survivors to join her onstage for an incredibly moving performance.

For his part, Biden has been extremely vocal about the importance of educating men on their duty to speak out against sexual assault and learn what consent actually means. "Being a man means respecting a woman's autonomy, not invading a woman's autonomy. You want to be a strong man? Respect," he said in an interview with Teen Vogue earlier this year.

If you or someone you know has been sexually assaulted, you can seek help by calling the National Sexual Assault Hotline at 800-656-HOPE (4673). For more resources on sexual assault, visit RAINN, End Rape on Campus, Know Your IX, and the National Sexual Violence Resource Center.
