Dr Luke has branded Kesha's claims she was offered her "freedom" in exchange for saying she lied about him sexually abusing her as a "publicity stunt".
The Tik Tok hitmaker suggested at the weekend she would be released from her exclusive deal with the producer and Sony Music if she made a public apology and now he has responded to insist her lengthy legal battle - which saw a court rule in February that she can't break their agreement, despite her allegations - has been all about "personal enrichment".
A spokesperson for the producer - whose real name is Lukasz Gottwald - said in a statement to Rolling Stone magazine: "The Court repeatedly stated Kesha is already free to record without Dr. Luke, and that she had not presented any facts supporting her claims.
"That's because all the evidence - including Kesha's own videotaped sworn testimony - show her allegations are false.
