Elon Musk points out 'mistake' in the meaning of his son's name

Elon Musk has publicly corrected his partner musician Grimes on Twitter after she made a mistake while explaining the meaning behind their newborn son's name.

Grimes gave birth earlier this week and the couple quickly became the talk of the Internet after they revealed the baffling name they'd given their son: X Æ A-12.

While the Internet has been trying to figure out how to pronounce the baby's name, Grimes took to Twitter to reveal the meaning behind it.

She wrote, "X, the unknown variable. 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 + (A=Archangel, my favorite song)."

Elon quickly corrected her, writing, "SR-71, but yes."

Grimes responded, "I am recovering from surgery and barely alive so may my typos b forgiven but, damnit. That was meant to be profound."

She also said the name sounds like the "main character in the story", adding, "I hope he vibes with that. Ok, going back into the pain/ beauty reverie for sum time, just came on to add my thoughts. Peace to all."

While the name has confused the world, it seems like the couple may face some trouble with the legality of naming him X Æ A-12.

TMZ reports a supervisor at the Department of Public Health Vital Records Office in Los Angeles has revealed it's illegal in California to include numbers or symbols in a name.

The law states that names must only include letters from the English alphabet and X Æ A-12 certainly doesn't meet that criteria.
