Elon Musk, the renowned entrepreneur behind companies like Tesla and SpaceX, has a large and diverse family. As of February 2025, Musk has fathered 13 children with four different women. His journey into parenthood began with Canadian author Justine Wilson, whom he met during his time at Queen’s University in Ontario, Canada. The couple married in 2000 and welcomed their first child, Nevada Alexander Musk, in 2002. Tragically, Nevada passed away at just 10 weeks old due to sudden infant death syndrome (SIDS).
Following this loss, Musk and Wilson turned to in vitro fertilization (IVF) to expand their family. In 2004, they welcomed twins Griffin and Xavier. Two years later, in 2006, the couple had triplets: Kai, Saxon, and Damian. This brought their total to five children together. The couple divorced in 2008, sharing custody of their children. In 2022, one of their twins, Xavier, came out as a transgender woman and legally changed her name to Vivian Jenna Wilson, adopting her mother’s surname and distancing herself from Musk.
In 2018, Musk began a relationship with Canadian musician Grimes. Their first child, a son born in 2020, was given the unique name “X Æ A-12.” Due to California naming laws, the name was later modified to “X Æ A-Xii,” with “X” as the first name and “Æ A-Xii” as the middle name. Musk has stated that the name is pronounced “X Ash A Twelve.” The couple’s second child, a daughter named Exa Dark Sideræl Musk, nicknamed “Y,” was born via surrogate in 2021. In 2023, they welcomed their third child, Techno Mechanicus, though details about this child have been kept private.
In 2021, Musk fathered twins with Shivon Zilis, an executive at his company Neuralink. The twins, named Strider and Azure, were born via IVF. Their existence was publicly revealed in 2022, highlighting Musk’s growing family.
Most recently, in February 2025, conservative influencer Ashley St. Clair announced that she had given birth to Musk’s 13th child five months prior. St. Clair stated that she and Musk had agreed to keep the pregnancy private to protect their child’s privacy. However, due to increasing media attention, she chose to disclose the relationship publicly. Musk has not directly commented on these claims.
While Musk’s professional life is highly publicized, he tends to keep his family life relatively private. However, some images of his children have surfaced over the years. For instance, photos of Musk with his twins Griffin and Vivian during public events are available. Additionally, images of Musk and Grimes with their son X Æ A-Xii have been shared on social media platforms. These glimpses offer a rare look into Musk’s personal life and his interactions with his children.
In summary, Elon Musk’s family comprises 13 children, each with unique backgrounds and stories. From his early experiences with Justine Wilson to his recent addition with Ashley St. Clair, Musk’s journey as a father is as multifaceted as his entrepreneurial ventures.
