Russell married actress Season Hubley, whom he met while filming "Elvis", in 1979, and had a son, Boston (born February 16, 1980). After his divorce from Hubley in 1983, Russell began his relationship with Goldie Hawn, and appeared alongside her in "Swing Shift" and "Overboard" having previously appeared with her in "The One and Only, Genuine, Original Family Band" in 1968. They have a son, Wyatt Russell (born July 10, 1986), and own homes in Vancouver, British Columbia; Snowmass Village, Colorado; Manhattan, New York; Brentwood and Palm Desert, California. Hawn's daughter with Bill Hudson, actress Kate Hudson, considers Russell to be her father. In an interview with People in December 2020, Russell revealed that he and Hawn never felt the need to marry, stating that a "marriage certificate wasn’t going to create anything that otherwise we wouldn’t have."
