Musician and son of Desi Arnaz and Lucille Ball. He served as the Drummer for the band Dino, Desi, and Billy.
He began playing drums when he was twelve years old.
Because his parents were the stars of I Love Lucy, his birth was worked into the television show's plot.
He married Linda Purl on January 13, 1980. Following his 1981 divorce from Purl, he wed Amy Arnaz. He has a pair of daughters named Julia and Haley.
The I Love Lucy character loosely based on Arnaz was played by Keith Thibodeaux.
