Tech entrepreneur Elon Musk has added another baby to his family. Neuralink Director Shivon Zilis announced on X that she and the Tesla CEO welcomed their fourth baby together. This little one makes baby number 14 for Elon.

In her post, Shivon revealed that she and Elon welcomed a son together named Seldon Lycurgus. She did not reveal when Seldon was born. She shared the news on their daughter Arcadia’s birthday, whose birth was announced in June 2024. “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.” She ended her post sharing a little bit about her fourth baby writing, “Built like a juggernaut, with a solid heart of gold. Love him so much.” Elon and Shivon also share a set of twins named Strider and Azure.

News of Elon’s 14th baby comes just two weeks after conservative journalist Ashley St. Clair claimed to have welcomed the SpaceX founder’s 13th child. She didn’t share any details about the baby in her announcement except that the little one was born “five months ago.” Since her claim, the author has come out with legal claims over the custody of their child, whom Elon has yet to publicly acknowledge, and the allegedly name and sex of their baby has been shared. They reportedly have a son named R.S.C.

In addition to his children with Shivon and Ashley, he shares three children with singer Grimes. The former couple share son X Æ A-12, 4, daughter Exa Dark Sideræl, 3, and son Techno Mechanicus, who goes by Tau, 2. Grimes has also been the news with claims over Elon ignoring their shared child’s “medical crisis.” In since-deleted posts on X, the singer wrote, “Plz respond about our child’s medical crisis. I am sorry to do this publicly but it is no longer acceptable to ignore this situation. This requires immediate attention.”
