Elon Musk is now a father of 12.
The Tesla CEO, the richest man in the world, and Shivon Zilis, director of special projects at his company Neuralink, have privately welcomed their third baby together.

Musk also shares three kids — X Æ A-Xii, 4, Exa Dark Sideræl, 2, and Techno Mechanicus, whose birth was confirmed in 2023 — with ex Grimes, 36.
The tech billionaire also fathered six children with ex-wife Justine Wilson Musk, 51.
In April, Musk jokingly reflected on his parenting journey. "Whoa," he wrote on X, "I just realized that raising a kid is basically 18 years of prompt engineering."
