Elon Musk tells Post new baby with Shivon Zilis was no ‘secret:’ ‘All our friends and family know’

Elon Musk welcomed a new baby with Neuralink executive Shivon Zilis earlier this year. But while the public is just finding out via media reports, the tech tycoon tells Page Six 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,” Musk told Page Six. “All our friends and family know. Failure to issue a press release, which would be bizarre, does not mean ‘secret.'”

The baby is Musk’s 12th child, and his thirrd with Zilis, who works for his brain implant company. The name and gender of the new baby have not been revealed yet. 

Musk has been outspoken about his concern over population decline.

The latest Musk child was revealed in a new piece by Bloomberg, titled, “Elon Wants You to Have More Babies,” focusing on his obsession with birth rates.

The article said Zilis declined to comment, and that Musk didn’t respond when asked about the child.

Musk told Page Six on Sunday, “Many countries are already well below replacement rate, and the trend is that almost all will be. This is simply a fact, not a ‘debunked theory.'”

He added that, “2.1 kids is replacement rate, and obviously the world as a whole will soon drop below that point.”

The Tesla mogul also sent us a link to statistics on fertility rates from the World Bank Group.

Musk previously welcomed twins Strider and Azure with Zilis, 38, in November 2021. The twins were born just one month before he and alt pop singer Grimes welcomed Exa Dark Sideræl, via surrogate.

The existence of Exa, also known as Y, came out in a Vanity Fair article when the child began crying as Grimes was being interviewed. The headline called the infant, “Her Secret New Baby With Elon Musk.”

In July 2022, Musk told us, “Bravo to big families,” and said that he wants “as many [kids] as I am able to spend time with and be a good father.”

The same year, he also tweeted, “A collapsing birth rate is the biggest danger civilization faces, by far.”

Grimes is currently suing Musk over parental rights to their three children.

Despite the messy custody battle, the Tesla mogul, 52, was spotted with his 4-year-old son, X (born X Æ A-12), at the Super Bowl in Las Vegas, the Tesla plant in Germany and, most recently, the Cannes Lions Festival in France.

He also shares twins Griffin and Vivian, and triplets Kai, Saxon and Damian with ex-wife Justine Musk. (The former couple’s eldest child, Nevada, died at 10 weeks of sudden infant death syndrome, or SIDS.)
