Elon Musk’s Daughter Discloses the Strange Way She Learned About the Possibility of Having Another Half-Brother

Vivian’s followers also shared their own interesting family stories in response. Some recounted learning about siblings through Facebook or other circumstances.

Musk welcomed Vivian with his first wife, Justin Wilson, in 2004. In April 2022, Vivian filed court documents to legally change her gender from male to female and took her mother’s maiden name, stating that she no longer wanted to be related to her biological father.

Musk’s family includes twins Vivian and Griffin, and triplets Kai, Saxon, and Damian from his relationship with Justin Wilson, who divorced him in 2008. He also has three children with singer Grimes: X Æ A-Xii (known as ‘X’), Exa Dark Sideræl, and Techno Mechanicus. Additionally, he had twins Strider and Azure with his Neuralink executive Shivon Zilis in 2021 and another unnamed boy in 2024.
