'Bachelor Party' actress and '80s music video star Tawny Kitaen's cause of death revealed

The cause of death for 1980s rock music video star Tawny Kitaen was revealed on Wednesday – five months after her death at age 59.

The Orange County Sheriff’s Department in California confirmed to several media outlets that the star's cause of death was dilated cardiomyopathy, a common type of heart disease. Other significant factors included mild coronary atherosclerosis and the medications mirtazapine, mirtazapine metabolite, alprazolam, acetaminophen, pregabalin and hydrocodone.

Kitaen, perhaps best known for her role in "Bachelor Party," died on May 7 in her home in Newport Beach, Calif.

In an Instagram post, her children Wynter and Raine Finley, whom she shared with her ex-husband, retired Major League Baseball player Chuck Finley, announced the actress' death.

"We are heartbroken and saddened to announce the death of our mom," children Wynter and Raine Finley wrote on Instagram back in May. "We just want to say thank you for all of you. Her fans and her friends, for always showing her such support and love. You gave her life everyday. We miss her and love her and we know her legacy will live on forever."
