( CNN ) -- Dr. Luke 's lawyer is going public with details of what the music producer alleges is Kesha 's attempt to extort him to get out of her recording contract . The attorney provided CNN with a segment from an email she contends shows Kesha 's mom threatened to make sex accusations public unless her daughter was released from her contract . Kesha accuses Dr. Luke of sexually , physically and verbally abusing her over the past decade in a lawsuit filed Tuesday that demands she be freed from the contract she signed with him when she was 18 . The harsh accusations in her complaint describe an alleged rape involving Dr. Luke allegedly drugging the singer after a party . The lawsuit says he 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 . '' Continuous criticism about her weight by Dr. Luke caused Kesha , 27 , to developed the eating disorder bulimia nervosa , which almost killed her , according to her complaint . To continue under his control is a threat to her life , it contends . Dr. Luke filed his own lawsuit against Kesha hours after hers was made public Tuesday , accusing the singer of extorting him to gain freedom from her recording contract . His lawyer , Christine Lepera , followed up Thursday with a statement to CNN that said 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 , '' Lepera said . That truth , Lepera said , is that Kesha lawyer Mark Gerago 's `` real goal is to get out of her contract , rather than vindicate these absurd and defamatory allegations . '' Dr. Luke `` has n't seen Kesha in years , '' Lepera said . `` This kind of cynical grandstanding in which false claims of abuse are used as a negotiating tactic insults real victims . '' Lepera provided to CNN what she said was part of an email that Kesha 's mother sent to Dr. Luke 's lawyer a year ago threatening to smear the producer 's reputation unless her daughter was freed from her contract : . `` Tomorrow I am going to start making public how Dr. Luke blackmailed me into giving him and Circuit publishing credit , on all songs I wrote on warrior , with Kesha and other writers and producers ... We , me and kesha and her friends ... are going to make all of this Really PUBLIC , in the next few days . Luke date raped Kesha when she was 18 . Nicky Hilton 's birthday ? Paris Hiltons house ? Luke gave Kesha pills ? She ended up naked in his hotel room 2 days later , no longer a virgin ? Do we want all this to come out ? either this Luke releases Kesha from all legal contracts , and gives me back all my publishing , or we , Kesha and I. tell the truth . '' Geragos responded to Lepera 's extortion charge in his own statement to CNN Thursday : . `` It is telling that Dr. Luke would twist an email from a horrified and justifiably angry mother threatening to tell the truth -- the truth ! -- about the predator that sexually assaulted her daughter . It is offensive -- but not surprising -- that Dr. Luke would try and pervert the words of a concerned mother to try and keep Kesha under his unilateral control against her will . '' 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 . 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 . She entered a rehabilitation center to be treated for the eating 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 . 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 .
