Billionaire Elon Musk and Neuralink executive Shivon Zilis announced the birth of their fourth child on Friday.
Zilis first shared the news in a post on X, writing: “Discussed with Elon and, in light of beautiful Arcadia’s birthday, we felt it was better to also just share directly about our wonderful and incredible son Seldon Lycurgus. Built like a juggernaut, with a solid heart of gold. Love him so much.”
Musk responded to her post with a heart emoji.
The pair had already welcomed three children together, twins Strider and Azure, and daughter Arcadia.
It comes weeks after influencer Ashley St. Clair said she had also welcomed a child with Musk.
“Five months ago, I welcomed a new baby into the world. Elon Musk is the father,” she wrote on X in mid-February, adding that she had not previously disclosed the news in an effort to protect the child’s privacy and safety.
Musk has not publicly acknowledged St. Clair’s claim.
Musk also shares six children with his first wife Justine Wilson: Nevada Alexander (who died at just 10 weeks of age), twins Griffin and Vivian, and triplets Kai, Saxon, and Damian.
The Tesla CEO also has three children with the musician Grimes: two sons, X Æ A-12 and Techno Mechanicus, and a daughter, Exa Dark Sideræl.
