The Two Wives: A Tale of Double Marriage and Divorce

Musk’s two marriages were marked by starkly different dynamics and outcomes. His first wife, Justine Musk (née Wilson), was a fellow Canadian and a promising author. Their relationship, which began in college, was a foundational one that produced six children—a twin set and a triplet set—via IVF after the tragic loss of their first son, Nevada Alexander.

The divorce from Justine in 2008 was acrimonious, with Justine later writing an influential essay about their relationship dynamics, describing it as a tumultuous "starter wife" experience. Their co-parenting relationship remains a focal point, particularly concerning their children's well-being and privacy.

Shortly after his divorce, Musk began dating English actress Talulah Riley. Their relationship was so intense that they married in 2010, only to divorce in 2012. In a highly unusual move, they remarried in 2013, only to divorce a second time in 2016. This on-again, off-again dynamic made them a tabloid fixture, with Riley referring to the relationship as a "re-do." Riley, known for her roles in films like Inception, has since moved on to other high-profile relationships, but her two marriages to Musk remain a unique chapter in celebrity history.

The High-Profile Girlfriends: Art, Film, and Public Drama

Musk's subsequent relationships brought him into the world of Hollywood and avant-garde music, increasing the public scrutiny of his personal life.

Amber Heard: The Brief, Intense Hollywood Romance

The relationship with actress Amber Heard, which spanned from 2016 to 2018, was arguably his most public and explosive, occurring shortly after his final divorce from Riley and Heard’s own messy divorce from Johnny Depp. The pair were photographed together at various high-profile events, and their romance was characterized by its intensity and brief nature. While they never married or had children, the relationship remains a frequently cited part of both their public narratives, especially given the context of the legal battles that followed.

Grimes: The Avant-Garde Co-Parenting Arrangement

In 2018, Musk began dating Canadian musician Grimes, a relationship that instantly captured global attention due to their seemingly disparate worlds—the billionaire tech mogul and the experimental pop artist. Their relationship was characterized by its unconventional nature, including their children’s unique names: X Æ A-Xii ("X"), Exa Dark Sideræl ("Y"), and Techno Mechanicus ("Tau").

Despite their initial split in 2021, their co-parenting relationship has been described as "very fluid." In late 2024 and early 2025, Grimes was in the news regarding a custody dispute, which she publicly referenced as a source of financial strain, indicating the continued complexity of their family arrangement.

The Latest Chapter: 14 Children with Four Mothers in 2025

The most recent and significant updates to Elon Musk's family tree occurred in early 2025, confirming a total of 14 children with four women, a fact that has dominated recent headlines and cemented his status as a figure of unprecedented family size in the tech world.

Shivon Zilis: The Neuralink Executive and Co-Parent

Musk’s relationship with Shivon Zilis, a high-ranking executive at his brain-chip company Neuralink, has been one of the most closely watched. In late 2021, they quietly welcomed twins. In a major update, Zilis announced in February 2025 that she and Musk had welcomed their fourth child together, a son named Seldon Lycurgus, bringing their total to four. Musk has publicly referred to Zilis as his "partner" in co-parenting, underscoring a professional and personal bond centered on their shared vision and family.

Ashley St. Clair: The Newest Mother

Simultaneously, the public learned of another new addition to the Musk family. In February 2025, right-wing political commentator and author Ashley St. Clair announced the birth of her son, Romulus, born in September 2024, claiming Musk was the father. This claim was later supported by a paternity report, confirming that Romulus is Musk's 13th child. The relationship and subsequent legal filings for child support, which St. Clair made public, introduced a new, high-drama element to Musk's already intricate family life. This unexpected revelation of a fourth mother and a 13th child just before the announcement of the 14th child with Zilis highlights the unique and often surprising nature of the billionaire's personal connections.

The complexity of Elon Musk's romantic history and expanding family—two ex-wives, multiple high-profile ex-girlfriends, and four co-parenting partners—reflects a personal life lived on a scale as grand and unconventional as his professional ambitions in space, electric cars, and artificial intelligence. The recent, confirmed count of 14 children with four women as of 2025 ensures that the public fascination with the "Musk Family Tree" will continue to grow and evolve.
