Elon Musk and Shivon Zilis are celebrating a double milestone: the arrival of their fourth child, a boy named Seldon Lycurgus, and the first birthday of their third child, Arcadia. Zilis broke the news on X, unveiling the newborn’s name in a heartfelt post tied to Arcadia’s celebration, though she kept the birth date under wraps.
“After chatting with Elon, we decided Arcadia’s birthday was the perfect moment to introduce our amazing son, Seldon Lycurgus,” Zilis wrote. “He’s a powerhouse with a heart of pure gold—I adore him.” Musk chimed in with a simple heart emoji, signaling his joy. Until now, the couple had kept details of their third and fourth children private, making this a rare peek into their growing family.
Reports peg Arcadia’s birth to early 2024, bringing Musk’s tally of children to at least 14. With Zilis, he shares twins Strider and Azure, plus Arcadia and now Seldon. Musk’s sprawling family tree spans decades and partners: his late son Nevada Alexander with first wife Justine Wilson in 2002, followed by twins and triplets via IVF with her, and three kids with musician Grimes. Recently, Ashley St. Clair claimed she bore Musk’s son five months ago—a claim he hasn’t addressed.
From Neuralink breakthroughs to fatherhood, Musk’s life remains a whirlwind of headlines. For now, the spotlight shines on Seldon Lycurgus, the latest addition to his ever-expanding brood.
