Elon Musk and his girlfriend, singer Grimes, have welcomed a baby boy. Before you run out looking for cute monogramed baby items hold up. You won't find any. Trust us.

Just after the Tesla CEO announced the birth on social media a fan inquired via a tweet as to the name. Quickly, Musk replied..X Æ A-12. Ok...what? Musk also shared a sweet photo holding the newborn with a filter over the child's face to look as if the child had tattoos on his face. Very Post Malone.

Finally Tuesday, Canadian singer Grimes, her real name is Claire Elise Boucher, tried to give some clarification as to the meaning because the unique name. In a Twitter post Grimes explained, "X" stands for the "unknowable variable," "Æ" is her "elven spelling" of artificial intelligence and/or love, and "A-12" is her and Musk's favorite aircraft. Makes sense right?

Twitter is now a buzz with theories on how exactly to pronounce the name. One guess is that the name is Xavier, with the tweet saying, “So I feel like a genius for breaking the code to Elon Musk and Grimes baby boys name. It’s Xavier. X-a, then 1 in mandarin is ‘yee’ and 2 is ‘er.’ Thank you for listening to me, a stable genius.”

Some have taken to breaking it down piece by piece. Cosmopolitan magazine referenced Dictionary.com in search of some translations.  Æ translates to “ash” but that the symbol is really pronounced like the A in “cat” or “bad.” (Grimes insists it’s pronounced as “ai” though.) The X in the name either gets its usual pronunciation OR translates to “variable,” the A-12 translates to “Archangel,” and the last name (hands down the most simple part) is Musk.

With that in mind, here are the suggested possible pronunciations the baby Musk's name:

  • “Ecks Ash Archangel Musk”
  • “Ecks Ai Archangel Musk”
  • “Variable Ash Archangel Musk”
  • “Variable Ai Archangel Musk”

Musk, who has 5 other sons named  Xavier, Griffin,  Damian, Saxon,  and Kai from his marriage to author Justine Wilson, may have some trouble with the name being legal. According to TMZ, California law states names must only include the 26 letters of the English alphabet. Since the child was born there and obviously the name is far from meeting criteria, the couple may need to resort to something basic like Dave or Mike.
