The world is getting a rare glimpse at the children of one of TV’s most beloved couples.

Lucie Arnaz Luckinbill, the daughter of I Love Lucy stars Lucille Ball and Desi Arnaz, shared photos with her “recalcitrant” brother Desi Arnaz Jr. in a post to Instagram over the weekend.

“Desi is alive and well, my friends,” the 73-year-old wrote in the caption. “Just likes to stay a bit ‘undercover.’” 

In her Aug. 3 post, the two can be seen smiling while Lucie embraces her brother’s arm and rests her head on the 71-year-old’s shoulder.  

Desi Jr., a Golden Globe-winning actor himself, has kept out of the spotlight in recent years after losing his wife, Amy Arnaz, to cancer in January 2015.

His last major red carpet event with Lucie was in 2011 at a tribute for I Love Lucy hosted by The Paley Center for Media in Beverly Hills.

This time, Desi Jr. was the “special guest,” as Lucie put it, during her recent trip to Las Vegas. She made the trek to Nevada to support her husband Larry Luckinbill at STLV: The 58-Year Mission, a Star Trek convention in which the actor, who appeared in the series, participated in multiple panels.

While Desi Jr. often stays out of the public eye, Lucie has shed light on the large impact he’s had on their family, especially when it came to their dad’s sobriety following the death of his second wife Edith Mack Hirsch.

"[My dad] resisted going into AA or any program for a long, long time,” Lucie told People in 2022. “But he finally did after his wife Edy died. He was just so upset that my brother convinced him, I think, 'Come on, Dad. You can do this.' And he did it. He stopped drinking."

The producer’s path to sobriety has been just one revelation learned about the legendary television star in recent years.

Arnaz and Ball were the subjects of the 2021 film Being the Ricardos and the 2022 documentary Lucy and Desi, which explored the couple’s marriage, divorce and monumental stardom they found following their successful sitcom.

Although her parents split in 1960 after 20 years together, Lucie said they had "unconditional love for each other."

"There was forgiveness. There was understanding,” she told People. “There was an appreciation for that other person and what you got from that other person, regardless of the stuff that hurt that never went away. And that was beautiful and that, in and of itself, was a wonderful thing to leave us."
