Grimes and Elon Musk have been forced to change their baby's name to comply with Californian law.
The 32-year-old singer - who gave birth to her son on May 4 - has revealed via Instagram that she's changed her baby's name from X Æ A-12 to X Æ A-Xii, because Californian law prohibits Indo-Arabic numerals in names.
The name change came to light after an Instagram follower asked: "Did you change the baby name because of Californian laws? What is the baby's new name?"
And Grimes replied: "X Æ A-Xii"
The music star subsequently added: "Roman numerals. Looks better tbh"
Under Californian law, names must be written on birth certificates "using the 26 alphabetical letters of the English language" - although apostrophes and dashes can be included, too.
The baby boy is Musk’s sixth son, as he has five other children, all boys, with his first wife, the Canadian author Justine Wilson.
People were left baffled when Elon revealed the baby’s name initially, with many quickly questioning how the name is even pronounced.
“How do you pronounce that?” one fan asked.
While another just wrote: “You’re joking.”
The pair have since fielded plenty of questions around the name including - the gender, meaning, and whether the name would be cleared legally.
Grimes wrote out the various meanings and symbols behind the name in a post.
•X, the unknown variable ⚔️— ꧁ ༒ Gℜiꪔ⃕es ༒꧂ 🍓🐉🎀 小仙女 (@Grimezsz) May 6, 2020
•Æ, my elven spelling of Ai (love &/or Artificial intelligence)
•A-12 = precursor to SR-17 (our favorite aircraft). No weapons, no defenses, just speed. Great in battle, but non-violent 🤍

Meanwhile, Grimes previously revealed she hopes her baby becomes a fan of raving.
The singer - whose real name is Claire Boucher - said: "Children need to get into raving, but I don't think I'll rave with my kid ... I don't think kids and adults need to rave together.
"But I wish I had discovered dance music at an earlier age. I don't have a problem with late bedtimes/nocturnalism. Unless there's some health risk I should know about.
"The baby has already been exposed to a lot of techno in the womb."
Grimes also revealed she wants to ensure her baby isn't "too spoiled".
She said: "I'll probably have to send them to live in the woods with my grandpa periodically so they aren't too spoiled. He's very intense. Lots of physical labour in the cold and whatnot, haha!
