Kesha says she was proposed a deal to obtain her "freedom" in exchange for an apology and a recant of her account of sexual assault, as she continues her legal battle against Dr. Luke.

The 29-year-old pop singer had sued the music producer in 2014 for sexual assault and battery and is seeking to invalidate her recording contracts with him. Dr. Luke, 42, filed a countersuit and called her allegations "defamatory." He also said he "didn't rape Kesha" and "have never had sex with her."

"So. I got offered my freedom IF i were to lie," Kesha said on Instagram Sunday, alongside a selfie of her looking somber. "I would have to APOLOGIZE publicly and say that I never got raped. THIS IS WHAT HAPPENS behind closed doors. I will not take back the TRUTH. I would rather let the truth ruin my career than lie for a monster ever again."
