Musk has six kids with his first wife, Justine Wilson. They met in college and fell in love. He later had three children with musician Grimes, his ex-girlfriend, while they were dating, which got a lot of attention. He just had three more kids with Shivon Zilis, who works as an executive at Neuralink, one of his other businesses.

Alexander Musk in Nevada

They got married in January 2000. Their names were Elon Musk and Justine Wilson. Their first child, a son named Nevada Alexander Musk, was born in 2002. Nevada died too soon by sudden infant death syndrome (SIDS) at the age of 10 weeks.

Flint and Vivian Musk

Musk and Wilson used IVF to have another child after losing their first child. Griffin and Vivian, their twins, were born in 2004. They are now 20 years old.

Vivian came out as transgender in 2022. She legally changed her name and stopped being close to Musk. She said she didn’t want to be “related to” her biological father anymore. Later, Musk said he was “tricked into signing” papers for her to change her gender, and he used her deadname and said, “My son Xavier is dead—killed by the woke-mind virus.” This caused a lot of controversy.

Kai, Saxon, and Damian Musk

They had three more children, sons Kai, Saxon, and Damian, who were born through IVF in January 2006. Each of the three is now 18 years old. They were the last children the couple had together before they split up in 2008.

X AE A–XII Musk

Musk started dating singer Grimes (Claire Elise Boucher) in May 2020. He had been married twice to Westworld actress Talulah Riley and had a short relationship with Amber Heard. In the same month, the couple had their son, X AE A-XII. X, who is now 4 years old, was first named X † A-12, but the name had to be changed because the characters “Æ” and “12” were not allowed in California.

In September 2021, Page Six was the only news source to say that Musk and Grimes were no longer together.

Dark Siderael Musk

Grimes told the public in March 2022 that she and Musk had their first daughter, Exa Dark Sideræl Musk, in December 2021 through a surrogate. She has a brother named X, so people call her Y. She is 2 years old now.

In an interview with Vanity Fair, Grimes called Musk her “boyfriend,” but she also said that their relationship was “fluid.” But she tweeted that they were no longer together hours after the story came out.

Grimes said on social media in March 2023 that her daughter goes by “Y,” “Why?” or even “?” but that the government won’t officially recognize the sound.

Strider and Azure

Court documents that Business Insider got in July 2022 show that Musk secretly had twins with Neuralink executive Shivon Zilis in November 2021. Their names, Strider and Azure, were made public in September 2023. They are now 2 years old.

An Austin, Texas judge agreed with Musk and Zilis’s request that the twins should have their father’s last name and part of their mother’s last name in their middle names.
