Hudson was married four times. Her first husband was Charles Brust. Little is known of the marriage other than it ended in divorce. She remarried in 1939 to Harold Thompson, who was the head of the Storyline Department at Disney Studios. She assisted Thompson, who was doing espionage work in Mexico as a civilian during World War II. They posed as a vacationing couple to various parts of Mexico, to detect if there was any German activity in these areas. One of their more successful vacations uncovered a supply of high test aviation gas hidden by German agents in Baja California.
After their divorce in 1947, she married a third time the following year to Los Angeles Times sportswriter, Dick Irving Hyland. The marriage lasted two years before the couple divorced. Her final marriage was to Robert Mindell, a hotel executive. The couple remained together for eight years before divorcing in 1971. She was actually born in 1916, but it would be unusual for a 15 year old to do romance, so they "made her older."
In 1972, Hudson died of pneumonia brought on by a liver ailment.
