New Baby Name Chosen By Elon Musk, Grimes Invalid Under California Constitution

SAN FRANCISCO (CNN) -- Elon Musk and Grimes might have told fans their newborn baby boy is called X Æ A-12 Musk but, it seems, the unusual moniker could fall foul of California state rules.

Names can only use the 26 alphabetical characters of the English language, according to the state constitution. Not only does this spell trouble for X Æ A-12 Musk, it also means bans on diacritical marks, such as accents in names like "José."

Musk owns multiple residences across California, including in Bel Air, Los Angeles and the San Francisco Bay Area, according to property tax records.

Tesla and SpaceX CEO Musk announced the birth of the couple's baby boy in a post on Twitter Tuesday, and Grimes later broken down each character of the name in a post of her own.

The Canadian musician -- real name Claire Elise Boucher -- explained "X" stands for "the unknown variable."

Meanwhile, "Æ" is the Elven spelling of AI, which is shorthand for artificial intelligence and translates to "love" in several languages, such as Japanese.

The 32-year-old star then shared that a part of her son's name is a reference to the couple's favorite aircraft.

"A-12 = precursor to SR-17 (our favorite aircraft). No weapons, no defenses, just speed. Great in battle, but non-violent," she added.

Grimes concluded the message by revealing that the "A" in the name also represents "Archangel," which she described as her favorite song.

However, Grimes apparently made a mistake in her explanatory post -- and Musk waded in to correct his partner.

"SR-71, but yes," he wrote in response.

The comment drew criticism online and Grimes herself wrote back: "I am recovering from surgery and barely alive so may my typos b forgiven but, damnit (sic). That was meant to be profound."

Perhaps realizing how the exchange came across, Musk then replied that his partner was "powerful."

As for the pronunciation, "It's just X, like the letter X. Then A.I. Like how you said the letter A then I," wrote Grimes on Thursday in response to a query on Instagram.

However, Musk told podcast host Joe Rogan a different pronunciation of the name in a conversation released Thursday, even as he credited Grimes for coming up with the moniker.

"First of all, my partner is the one that, actually, mostly, came up with the name," the Tesla and SpaceX CEO said. "Yeah, she's great at names."

Rogan then asked how to say it, to which Musk responded: "I mean it's just X, the letter X. And then, the Æ is, like, pronounced 'Ash'... and then, A-12, A-12 is my contribution."

This 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, and Rogan asked how it felt to have another child now.

"Actually I think it's better being older and having a kid," said Musk. "I appreciate it more. Babies are awesome."
