X Æ A-Xii Musk
Elon and Grimes's first child together; the name became a global conversation about naming conventions.
X Æ A-Xii Musk was born on May 4, 2020, to Elon Musk and Grimes (Claire Boucher). The name — pronounced by Elon as 'X Ash A Twelve' — sparked a worldwide debate and became one of the most covered celebrity baby name stories in recent memory. Grimes explained on Twitter that X represents the unknown variable, Æ is the Elven spelling of AI (her favorite aircraft and the AI element), and A-Xii references the Archangel 12 aircraft. California law initially rejected the name because of the special characters; the couple modified it for legal purposes to 'X AE A-XII' using Roman numerals. X has frequently appeared in social media posts and was seen on Grimes's back during a SpaceX event. Elon has spoken affectionately about him in interviews, calling him a 'great kid.'
