  • Grimes and Elon Musk have been the talk of the internet ever since they announced their new baby's name: X Æ A-12.
  • But the name fell afoul of California birth certificate rules—which bar the inclusion of numbers.
  • On Instagram, Grimes revealed the revised name: X Æ A-Xii.

Three weeks after welcoming baby X Æ A-12, Grimes revealed she and Elon Musk had changed their newborn's name, in accordance with California birth certificate rules which prohibit the inclusion of numbers. The new name's not all that different, and the pronunciation—which Grimes and Musk apparently haven't agreed on—is likely to be exactly the same.

In the comments of Grimes' latest Instagram post, one of her followers asked, "Did you change the baby name because of Californian laws? What is the baby's new name?" Grimes' response: "X Æ A-Xii." In a subsequent comment, she added, "Roman numerals. Looks better tbh."
