According to newly released court documents, it was revealed that Tesla founder Elon Musk secretly welcomed twins last year in November. The CEO fathered the twins with Shivon Zilis, who works as the project director at his Neuralink company.

The court documents showed that in April, the couple asked a county court in Texas (the state the twins were born) to change their twin’s names so they would “have their father’s last name and contain their mother’s last name as part of their middle name.” The gender of the twins was not revealed and their names were redacted from the document and remain unknown.

The twins were reportedly born in November of 2021, just one month before Elon and Grimes, a Canadian singer, welcomed their second child together via surrogate in December. The couple had not previously shared they were expecting another child and, in fact, announced their break up in September 2021. Grimes revealed they welcomed their second child in March when she appeared in Vanity Fair. At the time, Grimes shared that they named their daughter Exa Dark Sideræl, and that she would go by the nickname Y. However, she later revealed that the couple would be changing their daughter’s name and would not share their new choice. Elon and Grimes welcomed their first child together in 2020, a son named him X Æ A-Xii.

The twins are Elon’s ninth and tenth children. In addition to the two children he shares with Grimes, he is also father to Griffin, Damien, Kai, and Saxon. One of his children passed away at just 10 weeks old from sudden infant death syndrome (SIDS), a son named Nevada Alexander. Elon had an adult daughter who recently made headlines when she chose to change her gender and name: Vivian Jenna Wilson. Vivian changed her last name to Wilson, her mother’s maiden name, claiming at the time, ” I no longer live with or wish to be related to my biological father [Elon] in any way, shape or form.”
