Tennille, 73, whose real name is Cathryn Antoinette, filed for divorce from her 71-year-old husband an Arizona courthouse, claiming their marriage was "irretrievably broken", reported TMZ
The couple, married for 39 years, gave hits like 'Love Will Keep Us Together', 'Muskrat Love' and 'Do that to Me One More Time' in the 70s.
When contacted by the website about what caused the divorce, Dragon said, "I don't know why she filed. I gotta figure it out for myself first."
The divorce documents mention about health insurance coverage, and that seems relevant, because in 2009 Tennille had revealed that Dragon had been diagnosed with Parkinson's.
