Elon Musk's family tree explained as Tesla CEO becomes father for 14th time, welcomes 4th child with Shivon Zilis

Elon Musk's family tree: Billionaire tech mogul Elon Musk recently welcomed his 4th child with Neuralink executive Shivon Zilis.

His newest child, a boy named Seldon Lycurgus, is his 14th child.

With Zilis, Musk already has three children – twins Strider and Azure, and Arcadia.

“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,” Zilis posted on X (formerly Twitter) on Friday.

“Built like a juggernaut, with a solid heart of gold. Love him so much.”

The Tesla and SpaceX CEO responded with a heart emoji.

The announcement came just two weeks after influencer Ashley St. Clair claimed that Musk fathered her child.

On 14 February, Ashley wrote on X: “Five months ago, I welcomed a new baby into the world. Elon Musk is the father. I have not previously disclosed this to protect our child’s privacy and safety, but in recent days it has become clear that the tabloid media intends to do so, regardless of the harm it will cause.”

Ashley has also filed a paternity petition, seeking to have Musk legally recognised as the father.
