Biographie

Arnaz has a daughter, Julia Arnaz, from an undisclosed relationship.

At 17 he was dating actress Patty Duke, who was 23 at the time. The relationship became tabloid news and his mother did not approve of them together. After they broke up, writer and music producer Michael Tell offered to marry Duke as a way out of the scandal. Their marriage lasted only 13 days, and when Duke became pregnant, she would later tell her son, Sean Astin, that Arnaz was his biological father. Arnaz and Astin developed a close relationship, and although genetic tests later revealed Tell to be Astin's actual biological father, Astin remains close with Arnaz and Tell, as well as the father who raised him, John Astin, and his mother's third husband, Mike Pearce, saying, "I can call any of them on the phone any time I want to," says Sean. "John, Desi, Mike or Papa Mike...my four dads."

Arnaz was married to actress Linda Purl from 1980 until their divorce in 1981. On October 8, 1987, Arnaz married Amy Laura Bargiel. They lived in Boulder City, Nevada with their daughter, and own the Boulder Theatre, a cinema converted into a theatre and home to the Boulder City Ballet Company.

Desi's wife Amy died January 23, 2015, at the age of 63 from a long battle with cancer.
