Court documents obtained by Business Insider on Wednesday showed that Musk and the children’s mother, Shivon Zilis, filed to change the twins’ names to “have their father’s last name and contain their mother’s last name as part of of their middle name. ” The order was then approved by a federal judge in May. Zilis bought a house in the Austin, Texas area in August, nearly three months before the twins were born, according to Business Insider. Musk also owns a beachfront estate in the city. The twins were born weeks before Musk and his then-girlfriend, the musician known as Grimes, gave birth to their second child via surrogate in December. Zilis, 36, is director of operations and special projects for Neuralink, which develops computer chips for brain implants and where Musk is co-CEO. A graduate of Yale University, she began her career at companies such as IBM and Bloomberg Beta before joining Tesla in 2017 as a project manager. The Ontario, Canada native, who was named to the Forbes 30 Under 30 list in 2015, reportedly first met Musk that year through her work for his nonprofit OpenAI. The 51-year-old CEO has been an outspoken advocate for more births, expressing fear of a potential U.S. fertility crisis and touting his own birth success.

Most people I know have zero or one child.” “I mean, I’m doing my duty haha,” Musk said in a follow-up tweet to the thread last month. Musk has yet to shut down social networking platform Twitter, but Insider noted that Musk had Zilis on his list of people to run the company should the deal go through.
