The 4 Women & 14 Children: Unmasking Elon Musk's Complete 'Baby Mama' Saga (2025 Update)
The family life of tech mogul Elon Musk has become as complex and headline-grabbing as his ventures at Tesla, SpaceX, and X (formerly Twitter). As of late 2025, the billionaire is reportedly a father to 14 children with four different women, a rapidly expanding family that he has openly stated is part of his concern over global population decline. This is the complete, up-to-the-minute breakdown of the four women who are mothers to his children—often controversially referred to as his "baby mamas"—and the unique circumstances surrounding each relationship, including the contentious custody battles and the newest, most unexpected additions to the Musk lineage.
The latest updates from early 2025 reveal a new paternity dispute and the birth of a fourteenth child, cementing Musk's unconventional approach to family building. From his first wife, Canadian author Justine Wilson, to his complicated, on-again-off-again relationship with musician Grimes, and the professional partnership with Neuralink executive Shivon Zilis, the narrative is constantly evolving. The most recent and dramatic twist involves a conservative influencer and a high-profile paternity lawsuit that has captured public attention.
The Complete List of Elon Musk's Partners and 14 Children
Elon Musk has been married three times (twice to the same woman, actress Talulah Riley, with whom he has no children) and has had three other significant relationships that resulted in children. Here is a detailed profile of the four women who are mothers to his 14 children, known in the media as his "baby mamas."

The High-Stakes Drama: Custody Battles and Secret Paternity
The year 2025 has brought an unprecedented level of public drama to Musk’s family life, focusing on two of his partners: Grimes and the newly alleged mother, Ashley St. Clair. These legal and public disputes highlight the intense scrutiny and complexity of co-parenting with one of the world's most powerful figures.
The Grimes vs. Musk Custody Conflict
The relationship between Elon Musk and Claire Boucher, better known as Grimes, has always been unconventional, marked by their children's famously unique names: X Æ A-Xii (X), Exa Dark Sideræl (Y), and Techno Mechanicus (Tau). However, in early 2025, the dynamic turned openly hostile.
Reports surfaced of a contentious custody battle involving the three children. Grimes publicly claimed that Musk was actively blocking her access to the children and, in a bizarre modern twist, had even blocked her on his social media platform X. She has spoken out about the difficulties of co-parenting, even alleging that she had to beg him to stop ignoring a "child's medical crisis." This ongoing legal and public dispute, primarily playing out in the courts and on X, underscores the profound challenges of navigating a personal separation while sharing children with a media-dominant billionaire.
The Ashley St. Clair Paternity Suit: Romulus and the $15 Million Claim
Perhaps the most unexpected development of 2025 is the paternity suit filed by conservative influencer Ashley St. Clair. She announced in February 2025 via a post on X that Musk was the father of her son, Romulus, born in September 2024. The announcement quickly escalated into a legal battle.
St. Clair filed a legal petition for custody in the New York Supreme Court, claiming that Musk had offered her a one-time payment of $15 million to keep the child's paternity a secret. The public revelation and subsequent court battle, which Musk has reportedly made a surprise appearance in, confirm the high-stakes nature of his personal life. While the initial news was based on St. Clair's claims, reports indicate a high "Probability of Paternity" for Musk, adding Romulus to the growing list of his children and St. Clair to the list of his co-parents.
The Intentional Expansion: Shivon Zilis and the Newest Muske-teers
Musk's relationship with Shivon Zilis, a high-ranking executive at his neurotechnology company Neuralink, is rooted in their shared professional world and a mutual belief in the importance of a higher birth rate. Their family expansion has been largely private but steady, moving from twins to a total of four children in a remarkably short period.
The twins, Strider and Azure, were born in November 2021. Their birth was kept private until court documents revealed their names in 2022. The third child, Arcadia, was born in February 2024, with Zilis confirming the name on the child’s first birthday. The most recent and significant update is the birth of their fourth child, Seldon Lycurgus, reported in March 2025. This latest addition confirms Zilis as the mother of four of Musk's children, making her a central figure in his mission to promote a larger family size.
This pattern of co-parenting with Zilis, a professional colleague, is seen by many as a tangible manifestation of Musk’s public statements on the need for "smart people" to have more children to prevent what he calls a "civilization collapse." The children’s names—which also include the uniquely technical and mythological monikers of the Grimes children (X Æ A-Xii, Exa Dark Sideræl, Techno Mechanicus)—reflect the blend of futurism, technology, and classical history that defines Musk's world view.
Justine Wilson: The Foundation of the Musk Family
Long before the headlines about X, Y, and Tau, the foundation of the Musk family was built with his first wife, Justine Wilson. They met in college at Queen's University and married in 2000. Their family began with the tragic loss of their first son, Nevada Alexander, who died at 10 weeks old. This loss led them to use IVF, resulting in the birth of twins Griffin and Vivian in 2004, followed by triplets Kai, Saxon, and Damian in 2006.
Justine, an accomplished author, has been open about the complexities of their marriage and divorce, which ended in 2008. While her story is older, it remains the most substantial, accounting for six of Musk's children. The recent public news surrounding Vivian's name and gender change in 2022 also brought Justine's co-parenting relationship back into the spotlight, emphasizing the ongoing, real-world dynamics of their large, blended family.
The "baby mama" narrative surrounding Elon Musk is not just a celebrity gossip story; it is a complex, evolving saga involving four different women, 14 children with unique names, and high-profile legal battles over custody and paternity. The 2025 updates, particularly the ongoing Grimes custody drama and the explosive Ashley St. Clair paternity suit, ensure that the Musk family tree will continue to be a subject of intense public and media fascination for the foreseeable future.
