Earlier this month, Tesla and SpaceX CEO Musk announced the boy’s birth in a post on Twitter, revealing that his son was named “X Æ A-12 Musk”.
However, there has been speculation that the unusual nickname in California, where the couple lives, could violate the law because, according to the state constitution, names can only use the 26 alphabetical characters of English.
On Sunday, Grimes posted a new photo on Instagram that contains comments from fans.
“X Æ A-Xii” the singer wrote in response without confirming the reason for the change.
The singer also replied to another comment and said, “Roman numerals. Looks better, tbh.”
Grimes has previously broken down the meaning of the name for fascinated fans.
The Canadian musician – real name Claire Elise Boucher – explained that “X” stands for “the unknown variable”.
Meanwhile, “” “is the eleven spelling of AI, the acronym for artificial intelligence, and the word for” love “in several languages, including Japanese.
“A-12 = Forerunner of SR-17 (our favorite aircraft). No weapons, no defense, just speed. Great in combat, but non-violent,” she added.
The “A” in the name also stands for “Archangel”, which she described as her favorite song.
The fans were also intrigued by how to pronounce the name, and the happy couple seems to have different interpretations.
“It’s just X, like the letter X. Then A. I. As you said the letter A, then I,” wrote Grimes in response to an Instagram request.
Musk, however, said podcast host Joe Rogan had a different pronunciation of the name.
“I mean it’s just X, the letter X. And then the Æ is pronounced like ‘Ash’ … and then A-12, A-12 is my contribution,” he said.
X Æ A-Xii is the couple’s first child together. Musk has five other children – twins Griffin and Xavier, and triplets Damian, Saxon and Kai – from a previous marriage.
