London - Kesha's mother is countersuing Dr. Luke.
Pebe Sebert claims the music producer, who is also embroiled in a court battle with the 'Tik Tok' hitmaker, claims she suffered emotional distress and post-traumatic stress disorder after he allegedly raped her daughter in a way “not to be tolerated in civilised society.”
The 58-year-old singer also alleges the record executive - real name Lukasz Gottwald - acquired the name 'Dr.' because he used to deal drugs to celebrities when he worked as a guitarist on 'Saturday Night Live' for 10 years, and claims he boasted about taking girls out, getting them drunk and having sex with them.
She says the 41-year-old musician tormented and abused her by violating her daughter and she had to be medicated during a therapy session because she became hysterical when talking about him.
Her court documents largely restate claims made by Kesha in her lawsuit, according to gossip website TMZ.com.
The 27-year-old star filed legal papers in October seeking to have her record contract with Dr. Luke dissolved and accused him of sexually, physically, verbally and emotionally abusing her for almost a decade.
Shortly afterwards he filed a countersuit against the blonde beauty and also a separate lawsuit against her mother, claiming Pebe orchestrated a smear campaign of lies against him and tried to extort him in a desperate attempt to get Kesha out of her contract with him. - BANG Showbiz
