In more recent years, she ventured into the realm of reality TV, with appearances on shows including The Surreal Life, Botched, and Celebrity Rehab with Dr Drew.

Tawny later landed a series of music video roles including Whitesnake's Is This Love and Here I Go Again - and she went on to marry the band's lead singer David Coverdale in 1989.

However, the marriage only lasted two years, and they were separated in 1991.

She also went on to marry baseball star Chuck Finley, with whom she had two daughters, Wynter Merin Finley, 28, and Raine Finley, 22.

Tawny and Chuck were married in 1997, but went their separate ways in 2002.
