According to the petition, Vivian listed the reason for the changes as:

“Gender Identity and the fact that I no longer wish to be related to my biological father in any way, shape, or form.”


Vivian’s petition was granted in June 2022.

In October 2022, Musk broke his silence about his estrangement with Vivian. He told The Financial Times that his strained relationship with her may change in the future. But he said,

“I have very good relationships with all the others. Can’t win them all.”

Saxon, Kai, and Damian Musk

Musk and Wilson again turned to IVF and welcomed triplets Damian, Kai, and Saxon in January 2006. Musk’s teen sons just turned 17 years old.

All five of the older children have managed to stay out of the limelight mainly. They attended the private school Musk funded, Ad Astra, on the SpaceX campus.

Musk’s children and SpaceX employees’ children are the only enrollees in the school with a rich STEM curriculum. Robotics and artificial intelligence are heavy-hitting class options. But the school is said not to have a grading system.

Today the school is called Astra Nova. Their website landing page shares the following information:

“Born at SpaceX, Astra Nova is an experimental online school for kind, independent, and daring kids—available worldwide to students ages 10-14.”

Musk’s and SpaceX employees’ children are the only students at the Astra Nova school on the SpaceX campus.

Grimes and Musk started dating in 2018 and had a son in May 2020. They originally named him X Æ A-12, but California law didn’t recognize non-English alphabet characters or the number 12.

So his parents changed his name to X AE A-XII. Grimes pronounces the name “X A.I. Archangel,” but says they usually call him X. She also regularly refers to Elon as “E” or “Bro.”

Exa Dark Sideræl Musk

During the Vanity Fair interview, a baby’s cry interrupted the conversation. The sounds led to this question. “Do you have another baby in your life, Grimes?

At first, she hemmed and hawed, but then Grimes revealed that she and the world’s richest man, Musk, welcomed a daughter via surrogate in December 2021.

Exa Dark Sideræl Musk earned the nickname Y. In March 2023, Grimes tweeted a rare photo of her 15-month-old daughter. In a follow-up tweet to @grimesfeed saying hi to “baby sailor mars,” the musician said,

“She’s Y now, or “Why?” or just “?” (But the government won’t recognize that). curiosity, the eternal question, .. and such.”


So of course, social media was off — saying that the couple had changed the toddler’s name to a question mark symbol. Maybe they have, but that isn’t what the short tweet says.

In the Vanity Fair article, Grimes also calls Musk her boyfriend, saying:

Shortly after the article’s publishing, Grimes tweeted that she and Musk had broken it off again.
