The world’s wealthiest man Elon Musk reportedly has a 14th child, according to a woman who he already previously had three children with.

“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,” Shivon Zilis, an executive at Musk’s Neuralink, said in a post on X, formerly Twitter. It was unclear when the child was born.

This is a developing story and will be updated with additional information.
