NEW YORK — Pop star Kesha and producer Dr. Luke have settled nearly a decade of suits and countersuits over her accusation that he drugged and raped her and his claim that she made it up and defamed him, they announced Thursday, with the singer saying that “only God knows what happened that night.”

Dr. Luke, meanwhile, said he was “absolutely certain that nothing happened. I never drugged or assaulted her.”

Terms of the deal were not immediately disclosed, as both she and he revealed on Instagram that they had agreed to “a resolution” of the case and to a statement from each of them. Messages seeking comment were sent to their attorneys.

“I cannot recount everything that happened,” Kesha wrote, adding that she wishes “nothing but peace to all parties involved.”

Dr. Luke, in turn, said he wished her well and wanted “to put this difficult matter behind me” after years of fighting to clear his name.

The deal averts a trial that had been scheduled for this summer over allegations that became a #MeToo cause for Kesha’s supporters and came to involve a lineup of music industry luminaries. Lady Gaga, Kelly Clarkson, Katy Perry, Pink, Avril Lavigne, Adam Levine and Taio Cruz are among those who gave testimony or sworn statements related to the case.

At the same time, the case raised important legal questions about fame and defamation. The stakes were seen as high enough that media outlets weighed in about pretrial rulings that they worried could help powerful people suppress unflattering reporting.

The court clash between the multiplatinum-selling singer and the Grammy-nominated producer has been playing out since 2014 and looming over both of their careers.

The Associated Press does not generally name people who report being sexually assaulted unless they come forward publicly, as Kesha has done.

The singer made her name — originally styled Ke$ha — with a series of swaggering, just-try-to-stop-me party anthems, beginning with 2009’s “TiK ToK.” Those early hits were produced by Dr. Luke, who founded the record label that signed a Nashville unknown named Kesha Rose Sebert at age 18.

Born Lukasz Gottwald, he has produced chart-toppers for Perry, Lavigne, Flo Rida and more. Besides notching multiple Grammy nominations, Dr. Luke has repeatedly won pop songwriter of the year awards from the American Society of Composers, Authors and Publishers.

Kesha sued him in 2014, alleging he drugged and raped her nine years earlier and psychologically tormented her throughout their working relationship. She said he harangued her about her weight, denigrated her voice and lorded his power over her career.

“The abuse I suffered from Luke was a decade long, every day, every moment of every day,” she said during sworn questioning in 2017. According to Kesha, the ordeal sparked a flare-up of an eating disorder that led to her spending two months in a rehabilitation clinic in 2014.

Dr. Luke, who has not been charged with any crimes, responded by suing Kesha. He has asserted that she made “completely untrue and deeply hurtful” claims to tarnish him and get out of her record contract.
