"Duke was married four times and had three children.
In 1965, Duke married director Harry Falk, who was 13 years her senior.
During their marriage, she had repeated mood swings, drank heavily, became anorexic and overdosed on pills a number of times.[8]
The couple divorced in 1969.[8]
In early 1970, at the age of 23, Duke became involved with three men at the same time: 17-year-old Here's Lucy star Desi Arnaz, Jr.,[8] actor John Astin, who was 16 years her senior, and rock promoter Michael Tell.[35][36]
The relationship with Arnaz was widely publicized, due in part to the vocal and public opposition of Arnaz's mother, actress and production company executive Lucille Ball.
By late spring, Duke and Arnaz had broken off their relationship.
In June 1970, Duke learned she was pregnant and married Michael Tell on June 26, 1970..."
Their marriage lasted 13 days before ending in an annulment on July 9, 1970;[8]--Wikipedia
