Elon Musk is the father of 14 children, with births spanning from 2002 to 2025. According to People, the Tesla CEO’s family includes children with author Justine Wilson, musician Grimes, Neuralink executive Shivon Zilis and author Ashley St. Clair. His first child, Nevada Alexander, died at 10 weeks old from sudden infant death syndrome. Musk and Wilson later had twins Vivian and Griffin, followed by triplets Kai, Saxon and Damian, making the first chapter of his family life one marked by both loss and growth.
Justine Wilson Shares Musk’s First Six Children
Musk became a father in 2002 when Wilson gave birth to Nevada Alexander. After Nevada’s death, the former couple expanded their family through IVF and welcomed twins Vivian and Griffin, then triplets Kai, Saxon and Damian. Vivian later made headlines after legally changing her name and gender in 2022. In court documents cited by the source, she said she no longer wished "to be related to my biological father in any way, shape or form." Griffin has largely stayed out of public view, while Kai, Saxon and Damian have remained mostly private.
Grimes and Musk Share Three Children
Musk and Grimes welcomed son X Æ A-12 in May 2020, later adjusting the spelling of his name to X Æ A-Xii. They then had daughter Exa Dark Sideræl via surrogate in December 2021 and son Techno Mechanicus in June 2022. The pair’s children have occasionally drawn public attention, especially X, who has appeared with Musk at business meetings and political events. Grimes also spoke about her son’s fascination with space, saying, "X knows a lot about rockets. It's crazy," Grimes told People.
Shivon Zilis Welcomed Four Children With Musk
A separate branch of the family grew with Zilis, who shares four children with Musk: twins Strider and Azure, daughter Arcadia and son Seldon Lycurgus. Court documents first brought public attention to the twins, who were born in November 2021. Arcadia arrived in February 2024, while Seldon Lycurgus was announced in February 2025. Zilis later wrote about her son on X, calling him "our wonderful and incredible son Seldon Lycurgus." The births placed Zilis at the center of the most recent expansion of Musk’s family.
Ashley St. Clair Adds Another Chapter With Romulus
In February 2025, St. Clair said she and Musk had welcomed a child together in September 2024. The boy was later identified as Romulus. As reported by the source, a spokesperson for St. Clair confirmed both the child’s name and paternity test results. That made Romulus the 14th child publicly identified in Musk’s family timeline. The broader picture now stretches across several relationships, private disputes and public statements, with each new update adding another layer to one of the most closely watched family stories in celebrity and business circles.
