There is nothing funny about a new lawsuit implicating comedian Jim Carrey in the downward spiral of ex-girlfriend Cathriona White that culminated in her suicide. 

A wrongful death lawsuit against Carrey, filed by Mark Burton, the husband of Carrey's ex-girlfriend Cathriona White, alleges that the "Dumb and Dumber Too" comedian illegally obtained drugs under a fake name and provided them to White, according to media reports Monday. White was discovered in her apartment dead from an apparent suicide on Sep. 28, 2015 with multiple prescription drugs detected in her body. 

"This is a case about Defendant Jim Carrey using his immense wealth and celebrity status to illegally obtain and distribute highly addictive and, in this case deadly, controlled substances," the lawsuit reads. "After obtaining these drugs illegally and under a bogus name ("Arthur King"), Mr. Carrey proceeded to provide the prescription drugs to his 30-year old girlfriend, Cathriona White. Mr. Carrey did so despite the fact that he knew full well that Ms. White was ill equipped to ingest and manage highly addictive prescription drugs outside the care of a licensed physician. 

The lawsuit goes on to accuse Carrey, 53, of providing the drugs to White that ultimately killed her, claiming the prescription medication found near her body were labeled as belonging to the fake "Arthur King." Carrey allegedly covered up his involvement in White's death, including a text message to White about the drugs meant to conceal his knowledge of her condition, after failing to report that she was missing to the authorities. The lawsuit claims there was no way he could not have known that White planned to take the drugs and that his lack of action after noting that she had been missing for days with no contact was criminally negligent. 

Burton's lawsuit also claims that Carrey never paid for any of White's funeral expenses after publicly promising to do so. 

Four of White's friends found her body in her apartment after they hadn’t heard from her for several days. A toxicology report confirmed the death was suicide. The prescription pills propranolol, zolpidem, oxycodone and oxymorphone were found in her system.

White and Carrey broke up the week before she died. White addressed him in her suicide note, which was made public in July. "I've spent three days now in disbelief that you're not here," she wrote. "I can go on broken-hearted and try to put the pieces back. I could, I just don't have the will this time."

Carrey criticized the media for publicizing the suicide note. 

"When I came to Hollywood to make it as a comedian, I soon learned that the details of my private life would be handed out to the media like free dinner vouchers," Carrey, 54, said in a statement. "I never dreamed that the people I love most in the world would also be on the menu. What a shame."
