We don’t know if Elon Musk is joking or not, but if anyone would seriously name their child something like this… it’s him.
The Tesla founder announced the birth of his son with singer Grimes on Monday afternoon, telling fans on Twitter:

“Mom & baby all good”

Such great news! Congratulations!

When followers demanded the name, the inventor revealed his baby boy was going to be called:

X Æ A-12 Musk

Again, we have no idea if he’s on the level here or having some fun with his followers, especially considering the cute tatted up face photo that followed:
Don’t mess with that baby. / (c) Elon Musk/Twitter
Of course, if the name is real, it’s definitely in the running for craziest celebrity baby name of all time!
And lil X has some stiff competition in that race! So vote for yourself (below)!
