The First Wife: Justine Wilson and the Foundation of His Family
Musk's first marriage was to Canadian author Justine Wilson, whom he met while they were both students at Queen's University in Ontario, Canada. Their relationship began in the late 1990s, culminating in their marriage in 2000. This union marked the beginning of his journey into fatherhood and established the initial structure of the Musk family.
A Decade of Partnership and Tragedy
Justine Wilson, a fantasy author, provided a rare public glimpse into the challenges of being married to a man whose professional ambitions—at the time, PayPal and the nascent stages of SpaceX and Tesla—were all-consuming. Their marriage lasted eight years, ending in divorce in 2008.
The couple faced an early, profound tragedy: the loss of their first son, Nevada Alexander Musk, to Sudden Infant Death Syndrome (SIDS) at just 10 weeks old in 2002. This devastating event is often cited as a turning point in their lives, though they later expanded their family significantly through in vitro fertilization (IVF).
Between 2004 and 2006, Justine and Elon welcomed a set of twins, Griffin and Vivian Jenna, followed by a set of triplets, Kai, Saxon, and Damian. This resulted in six children from his first marriage. The divorce was highly publicized, with Justine Wilson later writing candidly about the experience and the dynamics of their relationship, offering one of the most detailed accounts of his early family life.
The Double Marriage: Talulah Riley and the On-Again, Off-Again Romance
Following his divorce from Justine Wilson, Musk entered into a relationship with British actress Talulah Riley. Riley is known for her roles in films like Pride & Prejudice and Inception. Their relationship was characterized by a unique pattern of commitment and separation, leading to two marriages and two divorces—all to the same person.
Two Weddings, Two Divorces
Musk and Riley first married in 2010. However, this initial marriage was short-lived, with the couple divorcing in 2012. Remarkably, they reconciled and remarried just 18 months later in 2013, a move that surprised many observers and highlighted the depth of their connection.
The second marriage lasted until 2016, when they finalized their second divorce. Talulah Riley has spoken positively about their time together, describing their relationship as intense but ultimately amicable, even after their final separation. They did not have any children together during either of their marriages. The repeated commitment to one another, despite the eventual separations, remains one of the most unusual chapters in Musk’s personal history.
The Modern Family: Co-Parenting with Grimes, Shivon Zilis, and Ashley St. Clair
In the years since his last divorce from Talulah Riley, Musk has not remarried, but his family has continued to grow through partnerships that reflect a more modern, non-traditional approach to family building. His focus has visibly shifted toward co-parenting with multiple partners, a dynamic that has consistently made headlines and expanded his family to 14 children as of late 2025.
Grimes: The High-Profile Artistic Union
Musk’s relationship with Canadian musician Grimes (Claire Boucher) began in 2018 and was perhaps his most high-profile romance with a celebrity. Their partnership, often described as a meeting of art and technology, resulted in three children, each with uniquely memorable names:
- X Æ A-XII (X): Born in 2020.
- Exa Dark Sideræl (Y): Born via surrogate in 2021.
- Techno Mechanicus (Tau): Born in 2022.
While their romantic relationship has been on-again, off-again, and is reported to be over as of 2025, they continue to co-parent their three children. Grimes and Musk have both been open about their commitment to raising their children in a supportive environment, despite the romantic separation.
Shivon Zilis: The Professional Partnership and Secret Twins
A significant development in Musk's family life came to light in 2022 when it was revealed that he had secretly welcomed twins with Neuralink executive Shivon Zilis in November 2021. The twins, Strider and Azure, were born just weeks before the birth of his second child with Grimes, Exa Dark Sideræl. Zilis, a director of operations and special projects at Neuralink, is a respected figure in the AI and tech world. This revelation highlighted Musk's commitment to expanding his family with partners who share his professional and intellectual interests, separate from any marital commitment.
Ashley St. Clair: The Latest Family Addition
The most recent and perhaps most unexpected addition to the Musk family was confirmed in early 2025. On February 14, 2025, political commentator Ashley St. Clair announced on X that she had recently welcomed Musk’s 14th child, a daughter named Esti, five months earlier. This news, which was initially a shock to the public, solidified the fact that Musk is actively pursuing his stated belief in increasing the birth rate to address population decline, often with partners who are not in a traditional marital relationship. The relationship with St. Clair, like his others, appears to be focused on a co-parenting dynamic, further illustrating his departure from conventional marital norms.
The Legacy of His Relationships and Topical Authority
Elon Musk's marital and co-parenting history is a fascinating study in modern celebrity relationships, blending traditional commitment with highly unconventional family structures. The journey from his first marriage to Justine Wilson, through the on-again, off-again dynamic with actress Talulah Riley, and into the current co-parenting arrangements with Grimes, Shivon Zilis, and Ashley St. Clair, paints a picture of a man whose personal life is as complex and boundary-pushing as his professional endeavors at Tesla, SpaceX, and X.
His relationships have produced a large, diverse family that includes 14 children with four different women, a fact that has made him a lightning rod for discussions about family, commitment, and the future of human population. Entities like his ex-wives, co-parents, and children (Nevada Alexander, Griffin, Vivian Jenna, Kai, Saxon, Damian, X Æ A-XII, Exa Dark Sideræl, Techno Mechanicus, Strider, Azure, and Esti) are all integral parts of the narrative. This unconventional path ensures that the topic of "Elon Musk marriages" and partners will remain a subject of intense public curiosity and media scrutiny for years to come.
