UPDATE: Linda Perry has apologized for her initial tweets.

EARLIER: Diane Warren has responded to allegations made by Linda Perry about Lady Gaga’s writing involvement with “Til It Happens To You,” the Oscar-nominated song from the documentary The Hunting Ground.

“‘Til It Happens To You’ was written for The Hunting Ground, an incredibly powerful documentary about sexual assault on college campuses,” Warren wrote on Twitter. “The song is the result of a special collaboration between myself and Lady Gaga. As Lady Gaga and I have [consistently] said. ‘Til it Happens To You’ was inspired by the countless survivors of abuse who need our support and love so they know they’re not alone.”

“Til It Happens to You” was honored with an Oscar nod last week, but singer-songwriter Perry claimed Sunday that Lady Gaga shouldn’t be listed as the track’s co-writer alongside Warren.

“I credit Diane for writing this song, it is her experience her pain her words,” Perry tweeted on Sunday night. “That’s it kids.” Perry alleged that Lady Gaga only contributed one lyric to the finished product.

“I love Gaga so much respect and love this song that has nothing to do with anything,” Perry wrote. “Why did Gaga get credit? Maybe because … Diane wanted to ensure her support in promoting the song. Gaga is a very smart business women she knew a song written by Diane Warren.”

Warren is an eight-time Oscar nominee, but she has never won the award despite writing some of Hollywood’s most famous movie songs (including “I Don’t Want to Miss A Thing” and “Nothing’s Gonna Stop Us Now,” among many others). Last year, she criticized singer Rita Ora for failing to support “Grateful” from Beyond the Lights, which was an Oscar nominee in the category.

“Gina [Prince-Bythewood], the director, wanted Rita to do it,” Warren said in an interview with The Huffington Post. “Had I known there wouldn’t be a lot of support, had I known she would have only tweeted about it once … you know? She sang it great, but it’s a little frustrating.”

At the time, Warren said there were other artists she had worked with who would have better supported “Grateful.”

“She sang it great!” Warren said of Ora. “But, come on. How on Earth are you not wanting to [promote it?] … I don’t get it. Everybody around me, we’re all shocked. How can … just … you know?”

Representatives for Lady Gaga did not respond to EW’s immediate request for comment.

Warren and Lady Gaga are up against David Lang’s “Simple Song #3,” Antony Hegarty and J. Ralph’s “Manta Ray,” Jimmy Napes and Sam Smith’s “Writing’s On the Wall,” and The Weeknd, Ahmad Balshe, Jason Daheala Quenneville, and Stephan Moccio’s “Earned It” for Best Original Song this year.
