(Newser) – Jim Carrey's on-and-off girlfriend Cathriona White was married to somebody else when she killed herself last year—and he is now suing the actor. Oregon man Mark Burton accuses Carrey of illegally obtaining the prescription drugs that killed the 30-year-old Irishwoman, USA Today reports. Burton, who filed a lawsuit for wrongful death and drug violations in Los Angeles on Monday, accuses Carrey of obtaining the drugs under the fake name Arthur King and giving them to White despite being aware that she suffered from depression and was "ill equipped to ingest and manage highly addictive prescription drugs." She left a suicide note addressed to Carrey.

Carrey has made it clear that he plans to fight the lawsuit, E! Online reports. In a statement, Carrey said it would be easy for him to make the lawsuit go away, but there are times "when you have to stand up and defend your honor against the evil in this world." "I will not tolerate this heartless attempt to exploit me or the woman I loved. Cat's troubles were born long before I met her and sadly her tragic end was beyond anyone's control," he said. "I really hope that some day soon people will stop trying to profit from this and let her rest in peace." Sources tell People that White and Burton were separated at the time of her death and that relatives in Ireland were unaware she even had a husband. (Read more Jim Carrey stories.)
