Meet Elon Musk’s Siblings: Asha, Kimbal, Tosca, Jana Bezuidenhout, Alexandra, & Elliot Rushi Musk

Elon Musk is one of the most talked-about businessmen in the world, but the spotlight on him often overshadows the fact that he comes from a large, complicated family.

Between his parents’ relationships and his father’s later unions, Elon has two full siblings and four half-siblings, each with a distinct story.

Elon Reeve Musk was born on June 28, 1971, in Pretoria, South Africa. He is currently 55 years old. His mother is Maye Musk, a Canadian-South African model and dietitian, and his father is Errol Musk, a South African electromechanical engineer, pilot, and property developer.

Elon holds South African, Canadian, and American citizenship and is of mixed European descent, largely British and Pennsylvania Dutch ancestry through his mother’s side, with Afrikaner and English roots on his father’s side. He does not follow an organized religion and has described his views as more spiritual or agnostic than tied to any particular faith.

Elon is the eldest of Maye and Errol’s three children, followed by Kimbal and Tosca. He attended Waterkloof House Preparatory School and Pretoria Boys High School in South Africa before moving to Canada at 17, where he enrolled at Queen’s University.

He later transferred to the University of Pennsylvania, earning degrees in economics and physics. He briefly began a PhD in applied physics at Stanford before leaving after two days to pursue business ventures, a decision that led to Zip2 and eventually PayPal, Tesla, SpaceX, and xAI.

Elon stands at 188 cm (6 feet 2 inches) tall. He has been married three times: to Justine Wilson from 2000 to 2008, and twice to English actress Talulah Riley, first from 2010 to 2012, then again from 2013 to 2016. He is not currently married.

Beyond his marriages, he has had high-profile relationships with musician Grimes and, more recently, a close co-parenting partnership with Neuralink executive Shivon Zilis.

Elon has fathered 14 known children across four women. With Justine Wilson, he had six children: firstborn son Nevada Alexander Musk, who died in infancy from SIDS, followed by twins Griffin Musk and Vivian Jenna Wilson (who was born Xavier Musk and later legally changed her name and took her mother’s surname), and triplets Kai Musk, Saxon Musk, and Damian Musk.

With Grimes, he shares three children: X Æ A-Xii Musk, Exa Dark Sideræl Musk, and Techno Mechanicus Musk, known as Tau Techno Mechanicus Musk. With Shivon Zilis, he shares four children: twins Strider Sekhar Musk and Comet Azure Musk, daughter Arcadia Musk, and son Seldon Lycurgus Musk, announced in 2026.

Conservative commentator Ashley St. Clair has also claimed Musk fathered her son, Romulus Musk, though his legal surname remains contested amid the ongoing paternity and custody dispute.

Musk’s net worth exceeds $800 billion, driven largely by his stakes in SpaceX, Tesla, and the merged SpaceX-xAI entity, cementing his position as the richest person alive following SpaceX’s public listing.

With that background in place, here is a closer look at the six people who make up Elon Musk’s sibling circle.

Kimbal Musk

Kimbal Musk is Elon’s younger full brother, born on September 20, 1972, in Pretoria, South Africa, to the same parents, Maye and Errol Musk. He followed a similar early path to Elon, eventually relocating to Canada and then the United States.

Kimbal built his own career away from his brother’s tech empire, co-founding several companies with Elon in the 1990s before shifting focus toward food and sustainability. He is best known today as a restaurateur and entrepreneur, having founded The Kitchen Restaurant Group and Big Green, a nonprofit dedicated to building learning gardens in schools.

Kimbal also sits on the boards of Tesla and SpaceX, keeping him closely tied to his brother’s business world even as he has carved out his own identity. He and Elon remain close, often described as trusted confidants who occasionally exchange business advice.

Tosca Musk

Tosca Musk is Elon’s younger full sister, the youngest of Maye and Errol’s three children together. She has built a career in film and media, working as a director, producer, and screenwriter.

Tosca is also known for co-founding Passionflix, a streaming platform dedicated to adapting romance novels into films and series. Like her brothers, she has spoken publicly about the close but boundary-conscious relationship the three siblings share, noting that family gatherings tend to stay focused on family matters rather than business, even though advice is available if asked for.

Tosca has remained one of the more visible members of the Musk family in entertainment circles.

Alexandra Musk

Alexandra Musk, sometimes known as Alexandra “Ali” Musk-Steuart, is one of Elon’s four younger half-siblings from their father’s side. She was born from Errol Musk’s marriage to Heide Bezuidenhout, which followed his divorce from Maye Musk.

Alexandra has kept a relatively private profile compared to Kimbal and Tosca. However, she has appeared alongside her father and siblings in family photos over the years, including public appearances with Errol in South Africa. She is one of two daughters Errol had with Heide during their on-and-off relationship.

Asha Musk

Asha Musk, who goes by Asha “Rose” Musk, is Elon’s other half-sister from Errol Musk’s marriage to Heide Bezuidenhout, making her Alexandra’s full sister and Elon’s half-sister.

Born in 1998, she is among the youngest of the Musk siblings and has pursued her own path outside the public eye associated with Elon’s businesses.

She made headlines in 2025 when she married Charl Laubscher in a wedding held at BOSJES Farm in South Africa. Reports noted that Elon did not appear to attend the ceremony, though his half-sister Tosca publicly congratulated her.

Jana Bezuidenhout

Jana Bezuidenhout holds an unusual place in the Musk family tree. She is Errol Musk’s former stepdaughter, the daughter of his ex-wife Heide Bezuidenhout from a previous relationship, which made her one of Elon’s stepsisters during Errol and Heide’s marriage.

In 2018, it was revealed that Errol had fathered a child with Jana, whom he had known and helped raise since she was four years old. The relationship drew significant controversy and reportedly strained ties within the wider Musk family.

Errol and Jana went on to have a second child together, meaning she is both a former stepsister to Elon and, through her children with Errol, connected to him as the mother of two of his half-siblings.

Elliot Rushi Musk

Elliot “Rushi” Musk is Elon’s half-brother, born from Errol Musk’s relationship with Jana Bezuidenhout. His birth in 2018 was the news that first brought the unconventional relationship between Errol and Jana to public attention.

He is the older of the two children Errol and Jana share, with a younger half-sister following in 2019. Rushi remains one of the youngest members of the extended Musk family and, like his mother, has largely stayed out of the public eye.
