Kitaen was best known as the sultry red-haired actress who appeared in rock music videos during the heyday of MTV. She became the rock world's "video vixen" after appearing on the cover of two albums from the heavy metal band Ratt and starring in several music videos for Whitesnake, including the 1987 smash song "Here I Go Again." The video, played repeatedly on the burgeoning music television network, featured Tawny performing cartwheels on the hood of a Jaguar.

She also starred as the fiancee to Tom Hanks' character in the 1984 comedy "Bachelor Party" and as Jerry Seinfeld's girlfriend in a 1991 episode of "Seinfeld." 

Other TV credits included a stint as co-host of "America's Funniest People" and she appeared on the reality shows "The Surreal Life" and "Celebrity Rehab with Dr. Drew," in which she revealed her struggle with substance abuse.

Just a few weeks after Kitaen's death, her younger brother Jordan Kitaen spoke to Fox News about their tight bond and opened up about one of their last discussions before her passing.

Jordan shared with Fox News how he encouraged Tawny to get closer to her faith prior to her passing.

"To me, my faith is central to who I am. I've always felt that that's what's always gotten me through difficult times. I've always felt like that would be a huge help in Julie's life to have a more robust spiritual connection," Jordan said at the time.

The star had a tumultuous personal life. She married Whitesnake singer David Coverdale in 1989, but the pair divorced two years later. She later married MLB pitcher Chuck Finley in 1997, with whom she had two daughters. The marriage was rocky and it ended in 2002.

According to Variety, she had several run-ins with the law, including a charge for cocaine possession in 2006 and driving under the influence in 2009.

Jordan acknowledged Tawny sought recovery in the past for her struggles. Leading up to her death, he recalled encouraging her to define her "higher power," a term used in Alcoholics Anonymous.

"I told Julie she can't do it on her own, none of us can," Jordan recalled. "She's been in recovery before so she knew the concept of a higher power. I told her, ‘The higher power thing is awesome but give it some substance. You can have an intimate relationship with Him if you so choose or you can reject him and embrace the world and all of its disappointments.’"

Jordan said the conversation was well-received by his sister and that he felt she "was actually growing in that area."

In addition to her iconic dancing, she was a "proficient artist," he said.
