The 59-year-old blonde actress explains in her autobiography "A Lotus Grows In The Mud": "'Swing Shift' was a bitter experience, but without it I might never have met Kurt. He is the love of my life and we're now one of Hollywood's longest-established couples," reports Internet Media Database.
"We are often asked why we have never married. I laugh it off and say, 'Been there, done that'. It didn't work for either of us."
Hawn started dating 54-year-old Russell in 1982 after meeting him on the set of "Swing Shift" following two broken marriages to Gus Trikonis and Bill Hudson. Russell was previously married to Season Hubley, mother of his son Boston.
