What to Know About the 4 Women Elon Musk Shares Children With

**Elon Musk’s Expanding Family: The Details Behind His 14 Children**

Elon Musk, the billionaire entrepreneur behind the electric vehicle company Tesla and space exploration venture SpaceX, is the father of 14 children born to four different women. This expansive family includes six children with his first wife, Justine Wilson; three kids with singer Grimes; and a pair of twins and two additional children with Shivon Zilis, a director at Musk’s brain implant company, Neuralink. Musk also recently welcomed his youngest child with Ashley St. Clair.

Musk’s journey into fatherhood began with Wilson, whom he married in 2000. Their union, which ended in divorce in 2008, produced six children during a relatively brief period. Their firstborn, Nevada, tragically passed away from Sudden Infant Death Syndrome (SIDS) when he was just ten weeks old. Speaking about her grief in a 2010 essay, Wilson described how their loss propelled them to pursue parenthood again through fertility treatments. Over the following few years, they welcomed twins, Vivian and Griffin, in 2004, followed by triplets—Kai, Saxon, and Damian—in 2006, all conceived via in vitro fertilisation.

In recent years, the dynamics between Musk and Wilson have come into focus amid the release of Alex Gibney’s upcoming documentary, “Musk.” Wilson alleges that Musk referred to the mothers of his children as “breeders,” a remark that’s sparked controversy and debate about the family’s dynamics. This month, Zilis took to social media to announce the abrupt end of her romance with Musk, raising questions about the complexities of his family relationships.

Moving on to Grimes, also known as Claire Boucher, Musk’s relationship with the Canadian musician began in 2018. The pair have had a series of breakups and reconciliations, branding their relationship “fluid.” They share three children: X Æ A-Xii, born in May 2020, and two others—Exa Dark Sideræl and Techno Mechanicus—who were born through surrogacy in subsequent years. Grimes stated in a 2023 interview that she values building a family culture with Musk, aiming to foster a supportive environment for their children despite their challenges in co-parenting.

Musk’s connection with Shivon Zilis, who works for Neuralink, has added to his fatherhood narrative. Twins, named Strider and Azure, were born in November 2021, just weeks prior to the birth of Grimes’ daughter. Zilis and Musk are believed to have welcomed two more children since then, continuing to navigate their unusual family circumstance. Recent discussions among Zilis and Grimes indicate an effort to align on parental responsibilities, particularly in light of their simultaneous introductions of children into this unconventional family setup.

In February 2025, Musk’s family expanded further when Ashley St. Clair revealed on social media that she had welcomed a child with him. Named Romulus, the child’s birth had remained private until St. Clair cited concerns regarding media scrutiny over their family. St. Clair is currently seeking custody of their son, and Musk has acknowledged the financial support he has been providing, although detailed discussions regarding parental roles remain complex.

With so many children, Musk’s relationships with the mothers have come under scrutiny. Grimes and Musk have been embroiled in legal battles concerning parental rights, with attempts to structure a more stable co-parenting situation. This high-profile court dispute concluded in August 2024, although specific details were sealed.

Wilson’s contributions to the recent documentary provide context to Musk’s past relationships, emphasising the emotional and psychological impacts of their time together. Furthermore, Zilis’s insights into her relationship with Musk—how it began and ultimately ended—paint a nuanced picture of a man who is navigating both his roles as a father and a partner.

Looking at Musk’s expansive family, it is apparent that his children and their mothers exist in an unconventional framework, shaped by his astronomical ambition and public persona. As the world watches closely, both Musk and the mothers of his children are striving to strike a balance between personal and professional lives, all while raising a growing number of offspring who may one day play significant roles in their father’s legacy.

This intricate web of relationships and parenthood defines not just Musk’s private life but also offers a glimpse into modern family structures, where companionship and co-parenting exist in diverse and often non-traditional forms. As Musk continues to push the boundaries in technology and exploration, his family story remains a topic of public fascination, reflecting both the challenges and joys of fatherhood in the spotlight.
