Lucie Désirée Arnaz, now 74, was born in July 1951 to Lucille and Desi just a few months before I Love Lucy started airing that October. She quickly followed in her parents’ footsteps, making her first screen appearances in her mom’s show The Lucy Show, with her first foray into TV stardom coming in 1968’s Here’s Lucy playing Kim Carter for six seasons. She has continued her work on TV for decades, her latest being in a 2020 episode of the revival of Will & Grace.

She has also appeared in films like 1980’s The Jazz Singer, for which she earned a Golden Globe nomination. In 2021, she also served as an executive producer for the Oscar-nominated Being the Ricardos with her brother. Her career also extends to the stage, making her debut in a production of Once Upon a Mattress in 1973, appearing in Broadway renditions of They’re Playing Our Song (1979), Lost in Yonkers (1992), Dirty Rotten Scoundrels (2006), and Pippin (2014).

From 1971-76, Lucie was married to Philip Vandervort Menegaux. In 1980, she tied the knot with actor and writer Laurence Luckinbill, and the two now live together in Palm Springs. They have three children together: Simon, 44, Joseph, 43, and Kate, 40. Lucie is also a mom to Laurence’s two sons from a previous marriage as well.

Desiderio Alberto Arnaz IV, now 72, was born in January 1953, with his birth written into I Love Lucy, becoming one of the most historic births in the history of television. Lucy’s pregnancy on the show (despite the word “pregnant” never being uttered by any of the characters) was a watershed moment in the representation of family life on TV.

He similarly followed in his parents’ footsteps as an actor, appearing in The Lucy Show with his sister and parlaying it into an extensive TV and movie career including the likes of TV shows The Brady Bunch, The Streets of San Francisco, The Love-Boat, Automan, and Matlock, plus movies including Billy Two Hats (1974) and Joyride (1977). He began his career as a drummer at the age of 12 with the band Dino, Desi & Billy, and is now the only surviving member of the trio.

Desi welcomed his first daughter, Julia, after a relationship with model Susan Callahan-Howe when they were just 15, and he didn’t come to learn of his paternity until over 20 years after her birth. He dated Patty Duke as a teenager, but Lucille disapproved and they broke up right as she became pregnant. She welcomed a son, Sean Astin, and told him Desi was his biological father, although it turned out to be her husband she was married to for 13 days, Michael Tell.

Desi was also briefly engaged to actress Liza Minnelli, attending the Academy Awards with her when she won for Cabaret. He then married actress Linda Purl in 1979, although they divorced just a year later. He then tied the knot in 1987 with Amy Laura Bargiel, welcoming a daughter named Haley with her before Amy’s death in 2015.
