Los Angeles ( CNN ) -- Kesha and Dr. Luke exchanged harsh accusations in lawsuits filed by the singer and producer Tuesday . Kesha 's civil complaint filed in Los Angeles claims that Dr. Luke sexually , physically and verbally abused her over the 10 years since he signed her as an 18-year-old artist . Dr. Luke 's lawsuit filed hours later in New York contends Kesha made up `` outrageous and untrue statements '' to extort him into releasing her from her recording contract with his label . Her lawsuit demands that she be paid damages for suffering he caused and that her contract with Dr. Luke , whose real name is Lukasz Gottwald , be declared void because of the abuse . Kesha , whose full name is Kesha Rose Sebert , was `` an intelligent , family-oriented , and joyful young woman '' before Dr. Luke `` showered her with promises of fame and fortune '' and induced her to sign a contract with him in 2005 , her lawsuit said . Instead of living a life of Hollywood glamor , she `` lived in a prison of his abuse , '' the lawsuit said . Her complaint accuses him of giving her a `` date rape drug '' that allowed him to sexually assault her while she was unconscious . He allegedly used constant verbal insults -- such as calling her `` a fat f -- king refrigerator '' -- `` to make her feel completely worthless and maintain complete control over her life . '' The abuse did n't end after her debut album sold more than a million copies in the United States in 2010 , her complaint said . `` For the past 10 years , Dr. Luke has sexually , physically , verbally and emotionally abused '' her `` to the point where Ms. Sebert nearly lost her life , '' it said . Kesha , 27 , developed the eating disorder bulimia nervosa , which almost killed her , because of the continuous criticism about her weight by Dr. Luke , according to her complaint . She entered a rehabilitation center to be treated for the disorder earlier this year , the lawsuit said . Her doctors concluded that the `` unrelenting emotional and psychological abuse '' by Dr. Luke caused her to suffer `` severe depression , post-traumatic stress , social isolation , and panic attacks . '' Continuing contact with him `` would be 'life threatening , ' '' the lawsuit said . Kesha 's lawyer Mark Geragos said her lawsuit `` is a wholehearted effort by Kesha to regain control of her music career and her personal freedom after suffering for 10 years as a victim of mental manipulation , emotional abuse and sexual assault at the hands of Dr . Luke . '' `` The facts presented in our lawsuit paint a picture of a man who is controlling and willing to commit horrible acts of abuse in an attempt to intimidate an impressionable , talented , young female artist into submission for his personal gain . Kesha is focused on moving her life and her career beyond this terrible time , '' Geragos said . Christine Lepera , the lawyer who filed the suit for Dr. Luke , said Kesha 's complaint `` is nothing more than a continuation of her bad and offensive acts . '' `` As set forth in the complaint that we have filed on behalf of Dr. Luke , Kesha and her mother are engaged in a campaign of publishing outrageous and untrue statements about Dr. Luke to third parties , including scurrilous and false statements of purported physical and mental abuse of Kesha , '' Lepera said . `` We are confident that Dr. Luke will prevail in all matters , and that our client will be awarded substantial damages for this malicious conduct , '' Lepera said . Geragos said the singer is ready to put the past behind her . `` This is just another pathetic and entirely predictable example of Dr. Luke 's continued abuse , and a misguided attempt to keep Kesha under his tyrannical control , '' Geragos said . `` This lawsuit has absolutely no basis in fact , the law or reality . Kesha is focused on reclaiming her voice and her freedom . She is determined to move on with her life and her career by putting this dark period behind her . ''
