The actor, 51, proposed to Amy Railsback in March 2009, less than six months after finalising his divorce from his wife of 16 years, Gretchen.
Bonaduce recently treated Railsback to a vacation in Hawaii, but she was left stunned when he revealed they were actually in Maui to wed in a surprise sunset ceremony.
The couple became man and wife on 22 November (10), reports the National Enquirer.
Railsback, who, at 28, is 23 years his junior, is Bonaduce’s third wife.
