Musk, 51, and Zilis, 36, filed court papers to request that their children’s names be changed to include Musk’s last name, according to redacted legal documents published by Insider. The petition called for their names to “have their father’s last name and contain their mother’s last name as part of their middle name,” a request that Insider said was granted earlier this year.
The twins were born shortly before the birth of Musk’s second child with musician Grimes, who welcomed a baby girl named Exa Dark Sideræl Musk via surrogate in December. Musk, who has 10 children and is the world’s richest man with a fortune of more than $200 billion, has been an outspoken advocate of raising the birth rate, tweeting in May that the birth rate in the US was “below the minimum sustainable levels for ~50 years.”
Tesla and Neuralink did not immediately respond to a request for comment from CBS MoneyWatch. On Thursday morning, after Insider’s report, Musk tweeted that he was “doing my best to help the underpopulation crisis,” claiming that “collapsing birthrates are the greatest danger facing civilization by far.” .

I am doing my best to help the underpopulation crisis.
A collapsing birth rate is by far the greatest danger facing civilization.

In another tweet, Musk said: “Hope you have big families and congrats to those who already have!”
Zilis, a graduate of Yale, joined Neuralink in 2017, according to her LinkedIn page. She is also a fellow at the Creative Destruction Lab, which she describes as a machine learning incubator at the University of Toronto in her resume, and serves on the board of the Vector Institute for Artificial Intelligence and the Alberta Machine Intelligence Institute.
Musk had six children with Canadian author Justine Wilson, who was married to Musk from 2000 to 2008. Their first child died of sudden infant death syndrome, or SIDS, when he was 10 weeks old, Wilson wrote in an article by Marie Claire. The couple then had twins followed by triplets.
Earlier this year, one of the twins requested to legally change their name and gender to Vivian Jenna Wilson, a request that was granted, with Vivian stating in court documents that she is “no longer living[s] with or desire to be related to my biological father in any way, shape or form.’
Musk also has two children with musician Grimes. The first, a boy named X Æ A-12, was born in March 2020, while the second was born in December, a few weeks after the birth of his twins with Zilis.
