And we've a picture of the baba and all

Elon Musk and Grimes have welcomed their first child together - and he has one heck of a name.

Musk first shared news of his newborn son's birth on Twitter last night with the message “Mom & baby all good.”

When asked for the baby's name, the billionaire entrepreneur answered: "X Æ A-12." (I mean, it could be a joke, right..?)

 

Musk was also asked to share a first picture of the baba, which he generously obliged.

 

Elon and Grimes have been dating for two years, and announced they were expecting back in January.

This is Musk's first child with Grimes though he is father to five sons from a previous marriage.

Grimes has yet to release a statement on her newborn. She recently spoke about not wanting to "gender" her baby.

Musk also hit headlines in movie news today as his SpaceX is collaborating with NASA and Tom Cruise to make the first ever feature film shot in outer space.
