Vice President Joe Biden will attend the Academy Awards on Sunday and introduce Lady Gaga's performance of "Til It Happens to You," an administration official confirmed to The Hollywood Reporter.

The singer is nominated for best original song for her and Diane Warren's composition from the documentary The Hunting Ground, about campus sexual assault.

Biden is a longtime advocate against sexual assault and domestic violence and the author of the 1994 Violence Against Women Act, and he will use the opportunity to call on everyone watching the Oscars broadcast to visit ItsOnUs.org to take the pledge to stand up, speak out and help change the culture around sexual assault. Biden has been one of the main advocates for the "It's On Us" campaign, which asks people to pledge to recognize that sex without consent is assault, intervene instead of standing by if an act of sexual assault is taking place and create an environment in which sexual assault is unacceptable and survivors are supported.

The video for Gaga's song included a link to the "It's On Us" website. The singer recently opened up about being raped as a teenager by a producer she was working with, speaking about the experience during a New York Times panel in December to promote The Hunting Ground.

“Because of the way that I dress, and the way that I'm provocative as a person, I thought that I had brought it on myself in some way, that it was my fault," Gaga told the panel.

"I didn't tell anyone for, I think, seven years," she added. "I didn't know how to think about it. I didn't know how to accept it. I didn't know how not to blame myself, or think it was my fault. It was something that really changed my life. It changed who I was completely."

In the best original song Oscar category, Gaga and Warren are up against songs from The Weeknd ("Earned It" from Fifty Shades of Grey), Sam Smith ("Writing's on the Wall" from Spectre), David Lang ("Simple Song #3" from Youth) and J. Ralph and Anohni ("Manta Ray" from Racing Extinction).

Biden isn't the first sitting vice president to attend the Oscars. In 1931, Vice President Charles Curtis attended the fourth Academy Awards on President Herbert Hoover's behalf.

First lady Michelle Obama also appeared live via video during the 2013 Academy Awards to present the Oscar for best picture to Ben Affleck's Argo.

Last month, President Barack Obama weighed in on the controversy surrounding the lack of diversity among this year's Academy Award nominees, saying, as many people have, that the Oscars debate is a reflection of a larger issue and question about inclusion: "Are we making sure that everybody is getting a fair shot?"

Obama said the film industry should do the same thing as other businesses and "provide opportunity to everybody."

The Vice President will attend the Oscars with his wife, Dr. Jill Biden.
