NEWPORT BEACH, Calif. (WKRC) - Officials have finally announced a cause of death for 80s rock music video star Tawny Kitaen, who died in her home on May 7 at the age of 59.

The model and actress famously appeared in multiple music videos for hair metal band Whitesnake and on multiple album covers for the glam metal group Ratt.

She also starred as the fiancée to Tom Hanks' character in the comedy "Bachelor Party," and as Jerry Seinfeld's girlfriend in a 1991 episode of "Seinfeld."

According to a spokesperson for the the Orange County Sheriff's Department, Kitaen died of dilated cardiomyopathy, a heart muscle disease. It was ruled a natural death.

The spokesperson noted other significant findings included clogged arteries, antidepressants, Xanax, Tylenol, a nerve pain medication, and hydrocodone (an opioid).

Kitaen had a tumultuous personal life, which included a brief marriage to Whitesnake's lead singer, David Coverdale, and a rocky marriage to baseball pitcher Chuck Finley, with whom she had two daughters. She also revealed that she struggled with substance abuse on the show "Celebrity Rehab with Dr. Drew."

"We just want to say thank you for all of you, her fans and her friends, for always showing her such support and love," Kitaen's daughters wrote on her Instagram account. "You gave her life everyday."
