Elon Musk now has a second son with Shivon Zilis, their fourth child together and the Tesla CEO's fourteenth overall, People reports.
Musk, whose growing family includes children with Grimes and Justine Wilson, was announced to be the father of a new baby boy on Friday (February 18). He and Zilis welcomed Seldon Lycurgus, who follows their older children, son Strider, and daughter Azure, 3, and second daughter, Arcadia, who was born last February.
Last month, the SpaceX CEO was sued by Ashley St. Clair, who claims to be the mother of Musk's thirteenth child, known as R.S.D. The conservative influencer wants sole custody of their alleged child together.
On Friday, Zilis, a Neuralink executive, joyfully shared the baby news on X, formerly Twitter.
"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 tweeted. "Built like a juggernaut, with a solid heart of gold. Love him so much ♥️"
Amid Musk's controversy with St. Clair, Grimes publicly called out the tech mogul in a since-deleted tweet over allegedly ignoring the "medical crisis" of one of their three children. The Canadian singer also previously requested that Musk keep their son, X Æ A-Xii, 4, out of the spotlight after he attended an Oval Office event in February.
Last October, it was reported that Musk purchased a $35 million compound in Austin, Texas for two of the three mothers of his then-11 children.
