Elon Musk and Shivon Zilis have twins named Strider and Azure, who are 2 years old.
Shivon Zilis says that choosing Elon Musk as a sperm donor was a "pretty f--king easy decision" because she admires him greatly. In Walter Isaacson's 2003 biography "Elon Musk," Zilis is quoted as saying, "If the choice is between an anonymous sperm donor or doing it with the person you admire most in the world, for me that was a pretty f--king easy decision." She adds, "I can't possibly think of genes I would prefer for my children."
Elon Musk has three children with singer Grimes: X Æ A-Xii, Exa Dark Sideræl, and Techno Mechanicus. The couple has had an on-again, off-again relationship since 2018 and have kept many details of their children's lives private.
