Twins Griffin and Vivian Jenna Wilson (formerly Xavier), 18 years old
After losing Nevada, Musk and Wilson — who were married between 2000 and 2008 — turned to IVF to grow their family.
Wilson gave birth to twin sons Griffin and Xavier Musk in April 2004.
In April, Xavier filed court documents to legally change from male to female and lose their last name, stating, “I no longer live with or wish to be related in any way to my biological father.”
Xavier Musk, 18, filed paperwork in Santa Monica, California, on April 18 to be known as Vivian Jenna Wilson, taking the maiden name of her mother Justine Wilson, who was married to Musk from 2000 to 2008 and 18- year-old twins Xavier and Griffin and 16-year-old triplets Damian, Kai and Saxon.
The transgender teen explained that they want to take their mother’s surname to distance themselves from their father, but have not commented on whether they will receive financial support from their father – whose $213 billion fortune has made him the wealthiest man in the world.

X AE A-Xii Musk, 2 years old
Musk began dating singer Grimes in May 2018 and she gave birth to their son X AE A-Xii in May 2020.
Their son was originally named X Æ A-12, but “Æ” and “12” violated California law, which prohibits the use of symbols in a name. The couple subsequently changed the spelling of their son’s name.
Instead of X Æ A-12, just a few weeks after the baby was born, they revealed that his birth certificate would be registered under the name X AE A-Xii – using the Roman numeral version of the number ’12’ and changing the character æ to AE.
The couple subsequently separated in September 2021.

Exa Dark Sideræl Musk, named Y, 1 year old
Grimes and Musk later welcomed their first daughter, Exa Dark Sideræl Musk, via surrogate in December 2021.
Grimes called Musk her “boyfriend” in a Vanity Fair interview, but after the interview was published, she took to Twitter to reveal that they had since broken up.
“Me and E have broken up *again* since writing this article,” she wrote on March 10. “But he’s my best friend and the love of my life.”
New twins, names unknown
It is revealed that Musk had been quietly having twins with one of his top executives weeks before welcoming a child with Grimes via surrogate mother.
In November, Tesla’s CEO, 51, had reportedly given birth to twins with Shivon Zilis, 36, the director of operations at Neuralink, Musk’s brain-machine interfaces company. Insider reported. He now has nine known children.
Musk and Zilis filed a petition in April to change the twins’ names so that “their father’s last name and their mother’s last name are part of their middle name,” the court documents said.
The twins were born in November, just weeks before Musk and Claire Boucher, the musician who performs as Grimes, gave birth to their second child via surrogate in December.
