When Elon Musk and Grimes announced their baby boy's name in early May, the internet went ballistic. The little one is called "X Æ A-12", Musk tweeted, and everyone had questions, one of the most important ones being whether the name was even legal under California law (the answer is no).

There were also questions on whether the celebrity couple is even serious about the highly unusual name, but it appears that they are.

On Sunday, a fan asked Grimes on her Instagram whether she changed the baby's name due to the California laws. "What is the baby's new name," the fan asked.

"X Æ A-Xii," Grimes replied.

The new name is slightly more in accordance with California laws, which states that official names can only be spelled using the 26 letters of the English alphabet, hyphens, and apostrophes. Spelling out number twelve in Roman lettering satisfies the condition of not using a number, even though it arguably makes the name even more unusual. However, the character "Æ" still isn't permitted — we can only venture a guess that, officially, it'll be spelled as "AE".

In any case, it appears that Grimes and Elon Musk are quite serious about the name, so...expect more memes.
