Grimes revealed the update — changing the name from "X Æ A-12" to "X Æ A-Xii" — on her Instagram on Sunday.
"Roman numerals. Looks better [to be honest]," Grimes wrote in the comment section of her most recent Instagram post. "[O]ne dash is allowed."
Grimes explained the baby's unique name earlier in May. X represents "the unknown variable," Æ the "elven spelling of Ai (love [and]/or Artificial intelligence)" and A-12 the precursor to her and Musk's favorite aircraft the SR-71.
"No weapons, no defenses, just speed. Great in battle, but non-violent," Grimes wrote on Twitter, adding that A also stood for "Archangel," her favorite song.
