Elon Musk Corrects Grimes' Explanation Of Son's Name And Grimes Fires Back

The two went back and forth on Twitter over a mistake in the description of little X Æ A-12 Musk's moniker.

Elon Musk chose the wrong time to correct Grimes’ explanation of their newborn’s name.

The couple, who announced the birth of their baby boy on Tuesday, chose an unusual moniker for their son: X Æ A-12 Musk.

Grimes explained the name in a tweet, saying that the X stood for “the unknown variable,” and that Æ was a reference to both love and artificial intelligence.

The singer also shared that the A-12 is a “precursor to SR-17 (our favorite aircraft). No weapons, no defenses, just speed. Great in battle, but non-violent.”

Unfortunately, she made a slight error in her tweet, which the SpaceX CEO was all too quick to point out.

“SR-71, but yes,” Musk said in a reply to his girlfriend’s tweet, correcting where she’d referred to their favourite reconnaissance aircraft as the SR-17.

Grimes had a quick comeback that put Musk in his place.

“I am recovering from surgery and barely alive so may my typos b forgiven but, damnit,” she said. “That was meant to be profound.”

Musk quickly tried to correct himself with an emoji-laden compliment.

If only the two would tweet out a video on how to pronounce their son’s name. Grimes did give it a little more context, saying that she thinks the name “sounds like the name of the main character in the story” and that “he vibes with that.”

At the very least, it sounds like something that would trend on Twitter.

But, of course, the most important thing is that mum, dad and little X Æ A-12 are happy and healthy.

The child is the first for Grimes and the seventh for Musk. He has six sons with his ex-wife author Justine Wilson, including a baby named Nevada Alexander, who died in 2002 at only 10 weeks old.
