Elon Musk likes to talk about the "underpopulation crisis." He’s not just tweeting about it either; he’s actively working to solve it himself. It’s a lot to keep track of. Honestly, every time you refresh your feed, it feels like there’s a new "Musk-eteer" in the mix. People get confused because the timelines overlap like a messy Venn diagram of tech executives and indie pop stars.
So, how many baby mothers does elon musk have exactly? As of early 2026, the count stands at four women.
This isn't just about gossip. It's about a man who has fathered 14 children (that we know of) and is currently navigating complex custody battles and legal petitions. From his first marriage in the early 2000s to a secret child with a conservative influencer revealed just recently, the family tree is sprawling.
The First Chapter: Justine Wilson
Justine Wilson was there before the rockets and the electric cars. She met Elon at Queen's University in Ontario. He was a sophomore; she was a freshman. He was persistent—the kind of guy who wouldn't take "no" for an ice cream date. They married in 2000.
Their first child, Nevada Alexander, was born in 2002. Tragically, he passed away at just 10 weeks old from Sudden Infant Death Syndrome (SIDS). It’s a heartbreak that Justine has written about movingly. They didn't wait long to try again, turning to IVF.
In 2004, they had twins, Vivian Jenna Wilson and Griffin.

Two years later, in 2006, they had triplets: Kai, Saxon, and Damian.
That’s five living children with Justine. But the marriage didn't last. By 2008, they were headed for a messy divorce. Justine famously wrote in Marie Claire that she was a "disposable" wife. Today, the relationship between Elon and his eldest daughter, Vivian, is famously strained—she legally changed her name and gender in 2022 to sever all ties with him.
The Grimes Era: Chaos and Sci-Fi Names
Then came Claire Boucher, better known as the musician Grimes. They made their debut at the 2018 Met Gala, and the internet basically melted. Their relationship was "fluid," to put it mildly.
They have three children together:
- X Æ A-Xii (born 2020): Everyone just calls him "X."
- Exa Dark Sideræl (born 2021): Born via surrogate and nicknamed "Y."
- Techno Mechanicus (born 2022): His existence was kept secret until a biography by Walter Isaacson dropped. They call him "Tau."
Currently, Musk and Grimes are locked in a legal battle over parental rights. It’s a reminder that even for a billionaire, co-parenting with an ex is rarely simple.

Shivon Zilis and the Neuralink Connection
This is where it gets kinda complicated. In 2021, just weeks before Grimes welcomed her second child via surrogate, a top executive at Musk’s company Neuralink, Shivon Zilis, gave birth to twins.
Their names? Strider and Azure.
Initially, people thought it might have been a surrogacy arrangement, but Zilis later clarified they used IVF. They didn't stop at two. In February 2024, they welcomed a daughter named Arcadia. Then, in early 2025, Zilis announced the arrival of their fourth child, a son named Seldon Lycurgus.
That brings the total to four children with Zilis. Musk has defended these births, basically saying he’s doing his part to help the birth rate.
The Newest Addition: Ashley St. Clair
The most recent name to join the list is Ashley St. Clair. She’s a conservative author and influencer who dropped a bombshell on X (the platform formerly known as Twitter) in early 2025.

She revealed that she and Musk had a son, Romulus, born in late 2024.
This one has turned litigious fast. By January 2026, the two are reportedly in a custody dispute. St. Clair recently sued Musk’s AI company, xAI, alleging that the Grok chatbot was used to generate explicit deepfakes of her. It's a wild, high-stakes drama that blends personal life with corporate technology.
Summary of the Musk Family (As of 2026)
| Mother | Number of Children | Notable Names |
|---|---|---|
| Justine Wilson | 6 (5 living) | Vivian, Griffin, Kai, Saxon, Damian |
| Grimes | 3 | X, Exa (Y), Tau |
| Shivon Zilis | 4 | Strider, Azure, Arcadia, Seldon Lycurgus |
| Ashley St. Clair | 1 | Romulus |
Why Does This Matter?
Beyond the tabloid headlines, how many baby mothers does elon musk have is a question that touches on his philosophy of pronatalism. He genuinely believes that smart people have a moral obligation to procreate. He isn't just a father; he’s an architect of a specific kind of future.
But it’s also a logistical nightmare. Imagine the holidays. Or the legal fees.
If you're trying to keep up with the billionaire's personal life, the best thing to do is watch the legal filings. Between custody battles with Grimes and the new litigation with St. Clair, the courtrooms are providing more updates than Musk’s own social media profile. If you're curious about the impact of these dynamics on his businesses, keep an eye on how these legal disputes intersect with his roles at Tesla and X.
