Elon Musk appeared to confirm that he was secretly welcoming twins with Shivon Zilis by tweeting that he is “doing my best” to help populate the Earth.
“Doing my best to help the underpopulation crisis. A collapsing birth rate is by far the greatest danger facing civilization,” he said wrote Thursday morning.
“Mark my words, unfortunately they are true.”
The Tesla founder, who is now a father of 10 children, also congratulated those with large families and hoped that others would grow their offspring too.
“Maybe Tesla should make a highly configurable Robovan for people and cargo?” Musk, 51, joked.
Documents obtained by Business Insider Wednesday showed Musk expanded his family in November 2021 to include Zilis, one of his top executives.
The outlet reported that Musk and Zilis, 36, had filed a petition to change the twins’ names to “have their father’s last name and their mother’s last name as part of their middle name.”
The warrant was reportedly approved in May by a judge in Austin, Texas, though the names of the children remain unknown.
The twins were reportedly born just weeks before Musk and now-ex Grimes welcomed their second child, a baby girl named Exa Dark Sideræl, via surrogate in December 2021. They also share 2-year-old son X Æ A-Xii.
Musk’s children with the musician join his five other living children: Griffin, Vivian Jenna, Kai, Saxon and Damian.
The SpaceX founder – who is currently dating ‘Britney Ever After’ actress Natasha Bassett – shares his additional children with ex-wife Justine Wilson.
After getting married in January 2000, he and the Canadian author welcomed son Nevada Alexander in 2002. Nevada died tragically of SIDS, or SIDS, after just 10 weeks.
