On Monday, the 28-year-old singer filed an amended complaint in her lawsuit against Dr. Luke (real name Lukasz Gottwald) to now include Sony Music Entertainment for allegedly supporting the 41-year-old music producer's behavior.
E! News has obtained a copy of the complaint, in which Kesha alleges that Sony "had knowledge of Dr. Luke treating female entertainers under his tutelage and supervision in the same manner as alleged here regarding (Kesha), which includes physical and emotional abuse."
She adds that Sony provided Dr. Luke with "unfettered and unsupervised access to vulnerable female artists beginning their careers and who would be totally dependent upon Dr. Luke for success."
Dr. Luke has also responded to the amended complaint in a statement, telling E! News, "It's a further pleading full of the same baseless and unsupported allegations and a claim that smacks of desperation. In our view the amendment is ill advised and does not serve the plaintiff in any way."
Sony Entertainment has yet to respond to E! News' request for comment.
Back in October 2014, Kesha filed a suit against Luke—along with his companies Kasz Money, Precription Songs, Where Da Kasz At? and Kemosabe Records—for sexual assault, sexual harassment, gender violence, civil harassment, intentional infliction of emotional distress and other causes of action.
"For the past ten years, Dr. Luke has sexually, physically, verbally and emotionally abused [her] to the point where [she] nearly lost her life," the lawsuit stated. "Dr. Luke abused [her] in order to destroy her self-confidence, self-image, and self-worth so that he could maintain complete control over her life and career."
The papers also stated that the alleged misconduct put the pop star, who entered treatment for an eating disorder in January 2014, at risk.
In response to Kesha's lawsuit, Dr. Luke filed his own suit against the singer, her mother Pebe and her newly hired management company Vector Management for defamation, breach of contract, tortious interference with contractual relationships. Luke also claimed the singer's allegations are "defamatory" and untrue and claimed the filing was part of a greater extortion plan in order to release Kesha from her contract.
"Kesha's lawsuit is a spectacular and outrageous fiction that will go down in flames. As the truth emerges, this sad and misguided smear campaign will only hurt Kesha," Luke's lawyer Christine Lepera told E! News. "This is hardly the first time that Kesha and her mother have threatened Luke with an extortionist scheme to ruin his reputation publicly unless he let her out of her contract. She did the same thing years ago."
