Dr. Luke sues Kesha’s mother Pebe Sebert

OHMYGOSSIP — Dr. Luke (Lukasz Gottwald) has filed a lawsuit against Kesha’s mother Pebe Sebert accusing her of orchestrating a smear campaign against him and extortion.

The music producer – who has been accused by the ‘Tik Tok’ hitmaker of sexually, physically, verbally and emotionally abusing her – has filed a lawsuit against Pebe Sebert, claiming she orchestrated a smear campaign of lies against him and tried to extort him in desperate attempts to get the 27-year-old singer out of her contract with him.

According to the documents, which were obtained by TMZ, Luke claims the showbiz matriarch wanted Kesha to break her contract but because it was so tight, she then fuelled her anger over the deal and urged her daughter to spread false claims he raped her in order to “shame” him into letting her out of the agreement.

When Luke refused to back down, he claims Pebe then made it clear they would continue making the allegations against him until he agreed to terminate the contract.

In the suit, the producer – who has already filed a defamation claim against Kesha – claims both the ‘Die Young’ hitmaker and her mother have admitted under oath that he never attacked the star.

He is seeking over $75,000 in compensatory damages and punitive damages on top of that.

It was recently revealed Kesha said they never had sexual relations and he never offered her drugs during a court deposition in 2011, but her lawyer, Mark Geragos, claims she was forced to lie at the time because the 41-year-old record label boss allegedly threatened her.

The blonde beauty was quizzed by lawyers about her relationship with Dr. Luke – real name Lukasz Gottwald – when they were both being sued by her former manager three years ago.

The ‘Blow’ singer, who sought treatment in rehab for an eating disorder in January, tried to resolve her issues with Dr. Luke privately before she decided to sue him in a bid to dissolve their contract.
