Tennille filed the legal docs in Arizona, claiming the marriage was "irretrievably broken."
Dragon told TMZ he didn't see it coming. "I don't know why she filed. I gotta figure it out for myself first." He also said they're still living together in the same house.
A blog post on the couple’s website was updated on January 16, stating, "The Captain & Tennille appeared to the public as them being the ideal model for a 'rock-solid' married pair. But almost all people naturally evolve over time, & sometimes hidden feelings start to be uncovered..."
They had a string of hits in the ‘70s, including "Love Will Keep Us Together," "Muskrat Love" and "Do That to Me One More Time."
Popular ‘70s singing duo Captain & Tennille, aka Daryl Dragon and Toni Tennille, are splitting after 39 years of marriage.
