Elon Musk tells Page Six 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 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.’”

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

Musk, 52, has been outspoken about his concern over population decline.

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.

The story said Zilis declined to comment and that Musk did not respond when asked about the newborn.

The billionaire tells Page Six, “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 adds that “2.1 kids is replacement rate, and obviously the world as a whole will soon drop below that point.”

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

The Tesla mogul previously welcomed twins Strider and Azure with Zilis, 38, in November 2021. They were born just one month before he and alt-pop singer Grimes had 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, 36, is currently suing Musk over parental rights to their three children.

Despite the messy custody battle, the SpaceX founder was spotted with his 4-year-old son, X (born X Æ A-12), at the Super Bowl in Las Vegas in February, the Tesla plant in Germany in March and most recently the Cannes Lions festival in France earlier this month.

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.)
