Desi Arnaz Jr.

Desi's wife Amy died of cancer in 2015, at the age of 63. Both Desi and Amy were followers of Vernon Howard and attended meetings of Howard's New Life Foundation in Boulder City. They also followed and have supported the spiritual writer Guy Finley (also one of Vernon Howard's students) and his Life of Learning Center for Spiritual Discovery.

On October 15, 2011, Arnaz performed in Babalu at the Coolidge Auditorium of the Library of Congress. The performance was in conjunction with the Library's Lucille Ball and Desi Arnaz Collection.

In 2007, Arnaz appeared at the 5th Annual TV Land Awards with his sister Lucie to accept the Legacy of Laughter award posthumously given to their mother.

From about 2002 to 2007, he was vice-president of the board of Directors of the Lucille Ball–Desi Arnaz Center in Jamestown, New York. He resigned over a dispute with the executive director over the center.

Between 1998 and 2010, he was touring with a new configuration of Dino, Desi & Billy called Ricci, Desi & Billy, featuring Arnaz reunited with Billy Hinsche, and joined by Ricci Martin (youngest son of Dean Martin). The group performs original material as well as the songs the original band performed.

In 1992, he played his father in the movie The Mambo Kings, based on a Pulitzer Prize-winning novel that he felt treated his father with respect. The film includes a scene in which Desi Jr., playing his father's character Ricky Ricardo, acts opposite his mother as Lucy Ricardo with film from the TV series intercut with the cast.

Arnaz has a daughter, Julia Arnaz, from a relationship with a model when he was 15 years old; Julia's relationship to Desi Jr. was proven by a paternity test in 1991.

Arnaz was married to actress Linda Purl from 1980 to 1981. On October 8, 1987, Arnaz married Amy Laura Bargiel. In 1997, Arnaz purchased the Boulder Theatre in Boulder City, Nevada, and brought it back to life, after being on the brink of extinction. The cinema was converted into a theatre and home to the Boulder City Ballet Company. They also lived in Boulder with their daughter Haley.

Arnaz's acting extended into the late 1980s with various appearances on television, and a leading role in the series Automan, which ran from 1983 to 1984.

In 1977, he was the lead in the film Joyride opposite fellow children of famous actors Melanie Griffith, Robert Carradine, and Anne Lockhart.

In 1974, Arnaz played the title role in the Western movie Billy Two Hats with Gregory Peck. In 1976, he appeared on two episodes of the television series, The Streets of San Francisco. Arnaz also appeared in a 1976 episode of Saturday Night Live (SNL) hosted by both Desi Arnaz and Desi Arnaz Jr.. The younger Arnaz played Ricky Ricardo while Gilda Radner played Lucy in spoofs of supposed ill-fated pilots for I Love Lucy. Although a part of I Love Lucy for the purpose of these SNL parodies, he did not portray Little Ricky in the classic sitcom, a role played instead by Keith Thibodeaux (Richard Keith (actor)).

Arnaz was subsequently involved with entertainer Liza Minnelli, another relationship of which his mother disapproved; Ball thought that the singer-actress was too old for her son and, because of Liza's perceived reckless lifestyle, not a good influence upon him. Arnaz accompanied Minnelli to the Academy Awards ceremony in March 1973 when she won the Academy Award for Best Actress.

Arnaz dated actress Patty Duke when he was 17 and she was 23. He accompanied Duke to the 1970 Emmy Awards ceremony where she won the Emmy for Outstanding Single Performance. 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, although genetic tests later revealed that Tell was his father. Astin said, "I can call any of them on the phone any time I want to ... John, Desi, Mike or Papa Mike ... my four dads." (Michael Pearce, Duke's husband after John Astin, was his step-father.)

From 1968 to 1974, Desi Arnaz and his sister Lucie co-starred opposite their mother in Here's Lucy as her children. In 1968, he had a guest-starring role as Jerry and Suzie's drum-playing friend Tommy in the episode, "The Hombre Who Came to Dinner: Part 2", from the show The Mothers-in-Law, executive-produced and directed by his father. In 1970, he appeared on The Brady Bunch episode "The Possible Dream".

At age 12, Arnaz was a drummer with Dino, Desi, & Billy. The others were Dean Paul Martin (son of Dean Martin) and Billy Hinsche. The band scored two hit singles with "I'm a Fool" and "Not the Lovin' Kind" in 1965.

Desiderio Alberto Arnaz IV (born January 19, 1953), known professionally as Desi Arnaz Jr., is an American actor and musician. He is the son of Lucille Ball and Desi Arnaz.

Arnaz is a native of Los Angeles, California. His older sister is actress Lucie Arnaz, who was born in 1951.
