Ke$ha Death Threats, Dr. Luke: Kill Dog, Sexual Abuse, Cheating & Abortion Lawsuit Blackmail

The legal battle between pop sensation Ke$ha and renowned music producer Dr. Luke continues - and things are getting even uglier.

Initially, several fans blamed the 41-year-old industry mogul for Ke$ha's severe eating disorder. Then in October 2014, the "Blow" songstress filed a lawsuit against Luke amid a slew of seedy allegations involving date rape, drug use, and even physicial and emotional abuse. Her lawyer Mark Geragos told TMZ several months ago:

"This lawsuit is a wholehearted effort by Kesha to regain control of her music career and her personal freedom after suffering for ten years as a victim of mental manipulation, emotional abuse and an instance of 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."

Luke later slammed Ke$ha with a countersuit. But the drama didn't end there.

According to the "Die Young" superstar, Luke is a VERY bad and morbid man. She just filed additional court documents, accusing Luke of threatening her innocent pet pup in the studio. Apparently, the hit-maker said he'd "kill" the dog if it came anywhere near him. He also took personal aims at her family, saying he'd discredit Ke$ha's mom Pebe Sebert from any songwriting work.

Oh, and he also tried blackmailing his wife into having an abortion. Supposedly he cheats on her all of the time, and went into vivid detail about such sexual escapades with Ke$ha (probably in hopes of also getting her into bed).

Wow.

Time for Luke to save some face and make his next big move. His attorneys tell TMZ that such shocking allegations are still totally false.

Stay tuned as more details develop.
