Elon Musk jokes after twin reveal: I’m ‘doing my best to help the underpopulation crisis’ – Marca English

Elon Musk joked when he revealed that he had two twins with one of Tesla's executives.

According to reports, Musk and Shivon Zilis welcomed twins last November.

Musk previously tweeted about the falling birthrate in the US.

"USA birth rate has been below min sustainable levels for ~50 years. (The) past two years have been a demographic disaster," Musk tweeted on May 24.

Previously, the billionaire also used his social media account to say "have kids."

Musk now has nine children, five with Justine Wilson, two with Shivon Zilis, and two with Grimes, the artist.

Elon Musk kept in secret the identity of the twins.

However, when the news broke, Musk tweeted: "Doing my best to help the underpopulation crisis. A collapsing birth rate is the biggest danger civilization faces by far."

Then he followed with: "I hope you have big families and congrats to those who already do!"

However, people commented on Musk's underpopulation post by blasting the billionaire for having sex with one of her employees and saying he wants to help the world.

"Imagine just knocking up co-workers and telling people you're just trying to help."

Another user attacked Musk's polygamy by replying: "Congratulations to those who have a large family with one woman, not like you, a large family with different women."

Shivon Zilis, 36, became a top executive at Neuralink.

Shivon Zilis met Elon Musk when she was working at Tesla as a Project Director, they have been close to each other ever since.

The twins were born just a few weeks before Musk and Grimes had their second child.

According to Business Insider, Elon Musk and Shivon Zilis petitioned to change the name of the twins.

The report says that the children will "have their father's last name and contain their mother's last name as part of their middle name."
