According to an article from the specialized site published on Wednesday, Elon Musk and Shivon Zilis, a 36-year-old Canadian, filed a request in April with a court in Texas to change the names of the two babies.
They wanted to give them the father's surname and, as a middle name, the mother's surname. Their request was approved by a judge, according to legal documents seen by Business Insider.
Shivon Zilis is the director of operations and special projects at Neuralink, a billionaire startup specializing in neural implants.
The twins were born weeks before Elon Musk's second child with musician Grimes in December. They christened her Exa Dark Sideræl Musk, and commonly call her "Y". Their boy born in 2020 responds to “X”, shortened from X Æ A-12.
“I would probably call him my boyfriend but we are very fluid,” said Grimes, real name Claire Boucher, in an interview with Vanity Fair in March. “We live in separate houses. We are best friends. We see each other all the time... (...) I don't expect people to understand."
The richest man in the world had six children with Justine Musk (née Wilson) in the 2000s, one of whom died a few weeks after birth.
One of them, a transgender girl, recently filed a formal request to change her surname along with her gender in order to sever all ties with her father, according to legal documents seen by AFP.
"I no longer live with my biological father and no longer want to be associated with him in any form whatsoever," wrote the young woman.
Born Xavier Alexander Musk, she asked to be called Vivian Jenna Wilson and thus take the maiden name of her mother, divorced from Elon Musk in 2008.
The 50-year-old has written posts on Twitter in the past criticizing the fact that transgender or non-binary people ask to be identified by specific pronouns, including this tweet from December 2020: “I absolutely support trans people but all these pronouns are aesthetic nightmares.
