In an eyebrow-raising statement posted on X last year, Musk said: "Doing my best to help the underpopulation crisis. A collapsing birth rate is the biggest danger civilization faces by far." The quirky businessman certainly wasn't joking, as he has fathered 11 children that we know of.
Musk welcomed Nevada, Griffin, Vivian, Kai, Saxon, and Damian between 2000 and 2006 with his first wife, Justine Wilson. Tragically, his firstborn son, Nevada, died from sudden infant death syndrome at just 10 weeks old.
He also shares three children with Grimes. X AE A-XII was born in 2020 while Exa Dark Sideræl was born via surrogate in 2021. Walter Isaacon's new biography of the billionaire revealed that the couple have a third child named Techno Mechanicus.
It's not known when Musk and Grimes welcomed Techno Mechanicus, or if they're romantically involved again. The singer has previously described their relationship as "fluid". However, Grimes recently filed a legal petition over parental rights of the three children she shares with the billionaire.
And in a surprising turn of events, it emerged earlier this year that Musk had secretly welcomed twins named Azure and Strider with Neuralink director Shivon Zilis. The twins were born in November 2021, while the nature of Zilis and Musk's relationship is unknown.
