The pop star and the vice president will hold a rally at the University of Nevada, Las Vegas, on April 7. The White House says they'll speak about the need to prevent sexual assault on college campuses.
The two teamed up at the Academy Awards in February. Biden got a standing ovation when he introduced the singer, who performed her Oscar-nominated song "Til It Happens to You" about sexual assault on campuses.
In addition to the Las Vegas rally, Biden is holding events at universities in Pennsylvania and Colorado during a weeklong focus on sexual assault prevention.
