Elon Musk and Grimes' new bundle of joy sent the Internet into a spiral of confusion when the couple announced that their baby boy's name is X Æ A-12.
It remains unclear whether or not they're trolling, or if the name is a code for another, more pronounceable one, but if they are being serious, the moniker won't be valid in the state of California where the baby was presumably born.
"In California, you can only use the '26 characters' of the English language in your baby name," family law attorney David Glass told People. "Thus, you can't have numbers, Roman numerals, accents, umlauts or other symbols or emojis. Although an apostrophe, for a name like 'O'Connor,' is acceptable."
