A fan commented on a post, asking Grimes whether they had changed the baby’s name.

“Did you change the baby name because of Californian laws?” the fan asked. “What is the baby’s new name?”

Grimes revealed that they had indeed changed the name from X Æ A-12 to X Æ A-Xii.

“Roman numerals,” she explained. “Looks better tbh.”

Previously, in an interview with Joe Rogan, Musk explained the name.

“It’s just X, the letter X, and then the Æ is pronounced ‘Ash’ and then A-12 is my contribution,” he said. “Archangel 12, the precursor to the SR-71. Coolest plane ever. It’s true.”

Grimes also went deeper on the name in a tweet earlier this month.
