Who Are Elon Musk's Baby Mamas? He's Welcomed a 12th Child

Business magnate Elon Musk is officially a father to 12 children.

The wealthiest person in the world and one of his top executives at Neuralink welcomed their third child in June, just under two years after the pair welcomed twins. Though Elon is arguably better recognized for fathering children with popular musician Grimes, she has only given birth to three of his 12 total offspring. Let's break down who each of his baby mamas are (and how many children he has with each).

Elon's first baby mama is none other than his first wife, Justine Musk (née Wilson).

She is a Canadian author, best known for her 2005 contemporary fantasy novel, BloodAngel. The pair met while attending Queen's University in Ontario, Canada, and eventually tied the knot in January 2000.

In 2002, Elon and Justine welcomed their first child, Nevada Alexander; however, their son died of Sudden Infant Death Syndrome at just 10 weeks old. After losing their firstborn, the former couple turned to IVF. In 2004, Justine gave birth to twins Griffin and Vivian. Two years later, the novelist gave birth to triplets — Kai, Saxon, and Damian — via IVF.

Elon and Justine divorced in 2008.

Following his split from actress Amber Heard, the Tesla CEO began dating Canadian singer Grimes in May 2018. She's released five studio albums, amassing a large fandom due to her eccentricity and versatility as an artist.

According to Page Six, the former couple met via Twitter after discovering that they both tweeted the same pun relating to Rococo and the thought experiment Roko's basilisk. Wow, talk about an unexpected pairing.

In May 2020, Grimes gave birth to her and Elon's son, X AE A-Xii. He was initially named X Æ A-12, but his name was changed to adhere to California's naming laws.

Elon and Grimes broke up in September 2021; however, the "Genesis" vocalist revealed in March 2022 that she and the 51-year-old billionaire welcomed baby No. 2, a daughter called Exa Dark Sideræl, via surrogate. In 2023, they welcomed their third child, Techno Mechanicus.

The exact timeline of Elon's relationship with Grimes is a bit unclear, though it's obvious that while they were seeing each other, Elon was also seeing baby mama No. 3, as the birth dates for many of the singers' children overlaps with Elon's other new additions to the family.

On July 6, 2022, Business Insider reported that Elon welcomed twins in November 2021 with one of his top Neuralink executives, Shivon Zilis. According to the court documents obtained by the outlet, the pair requested to change their children's names to "have their father’s last name and contain their mother’s last name as part of their middle name."

The founder and CEO of SpaceX has publicly stated following the birth of his first children with Shivon that he's "Doing [his] best to help the underpopulation crisis," arguing that "a collapsing birth rate is the biggest danger civilization faces by far."

In June 2024, Elon confirmed that he and Shivon welcomed another child, though did not disclose the child's name or gender.

"All our friends and family know. Failure to issue a press release, which would be bizarre, does not mean 'secret.," he told Page Six of the most recent birth.

According to her official Twitter account, Shivon hails from Canada but currently resides in San Francisco. She attended Yale, studying economics and philosophy; she also played on the ice hockey team as the goalie before graduating in 2008.

Since then, Shivon has climbed her wait to the top of the corporate chain. She currently serves as the director of operations and special projects for Neuralink. She is also a board member for OpenAI.

Shivon worked as the project director for Tesla from May 2017 to August 2019 — per her LinkedIn, she worked on all of the AI projects. Perhaps that is how she met her baby daddy! Just how involved Elon is in these kids' lives isn't known, though it's safe to say 12 children is a lot to handle.
