Musk also shared a picture of the child. 

Anyway, as you can imagine, the name of the child has caused quite a stir on Twitter. 

Turns out, the name has special meaning for the couple, as the mother of the child, Grimes explained on Twitter. 

 'X' stands for "the unknown variable, 'AE' is the musician's 'elven spelling of Ai (love &/or artificial intelligence),' 'A-12' is, as gathered, a reference to the Lockheed A-12, the 'precursor to [the] SR-17 (our favourite aircraft). No weapons, no defences, just speed. Great in battle, but non-violent.

Here's the tweet for you:

Anyhow, that is going to be a problem for anyone to pronounce.
