Lady Gaga will appear Saturday at the 27th Annual Producers Guild Awards to perform “Til It Happens to You,” her Oscar-nominated song from the documentary “The Hunting Ground.”

Producer Amy Ziering will accept the film’s 2016 Stanley Kramer Award during the PGA’s ceremony at the Hyatt Regency Century Plaza in Los Angeles. “The Hunting Ground” deals with the issue of campus rape.

The film is written and directed by Kirby Dick and produced by Ziering. “Til It Happens to You,” written by Diane Warren and Gaga, is up for best original song at the Academy Awards.

“Well beyond her status as one of the most exciting performers working today, we admire and appreciate Lady Gaga’s commitment as an outspoken advocate for those whose voices often go unheard. In her activism, she truly embodies the spirit of Stanley Kramer, and we are doubly honored to have her join us in honoring ‘The Hunting Ground’ in his name,” said Producers Guild Awards Co-Chairs Michael De Luca and Jennifer Todd.

Linda Perry slammed the singer Monday on Twitter, accusing her of not writing the song.

“Normally I wouldn’t respond to all this but I don’t know Im feeling spunky,” she wrote. “There was another artist that originally was gonna sing #TIHTY.”

She later backpedaled and apologized.

“I made a mistake to comment,” she said. “I wasn’t in the room when the #TIHTY was being written. More importantly, I wish the focus to remain on the great importance of the song and the message of the film.”
