Tesla CEO Elon Musk, widely known for his concerns about population decline, recently welcomed his twelfth child, reports Bloomberg. The baby’s mother is Shivon Zilis, director of special projects at Musk’s brain-implant company Neuralink. Name and sex of the new baby has not been announced yet.

Elon Musk welcomes his 12th child; says new baby with Shivon Zilis was no 'secret' and doing this would have been "bizarre"

His latest child was first revealed in a Bloomberg article published Friday and titled, “Elon Wants You to Have More Babies,” focusing on his obsession with birth rates.

While the news surprised the public, Musk insists the birth wasn’t a secret. In a statement to Page Six Musk that a press release would have been unusual, and close friends and family are aware. The tech billionaire told Page Six exclusively that his latest bundle of joy was far from a “secret” — adding that issuing a press release would’ve just been “bizarre.”

“As for ‘secretly fathered,’ that is also false,,” he says. “All our friends and family know. Failure to issue a press release, which would be bizarre, does not mean ‘secret’,” he added.

Elon Musk’s third child with Zilis

This is reported to be Musk’s third child with Zilis, following twins born in 2021. He also shares children with musician Grimes, including a daughter born via surrogate in late 2021. Grimes is reported to be currently suing Musk over parental rights to their three children.

The news comes amid a Bloomberg article highlighting Musk’s focus on birth rates. Musk defends his views, stating that many countries are below replacement rates and the global trend suggests further decline. He emphasizes that a 2.1 birth rate is needed for population stability, and the world is likely headed below that point.
