Elon Musk and Grimes welcome baby, who Musk says is named ‘X Æ A-12 Musk’

Musk announced the arrival early on Tuesday morning on his Twitter account, saying mom and baby were ‘all good.’

Pop artist Grimes and her partner, SpaceX founder and CEO Elon Musk, have welcomed a baby in the world, according to photos posted to Musk’s Twitter feed late Monday night and early Tuesday morning.

Musk tweeted out that the baby’s name is X Æ A-12 Musk, though it’s very unclear if he was serious or not. (He also shared a photo of the baby with fake tattoos superimposed on the child’s face.)

Musk shared that both mom and baby were “all good.” The news actually broke in a Twitter thread that was originally about a Tesla testing issue, but quickly pivoted to hearty congratulations for the new parents.

Here are the tweets:

Congratulations to the new parents.
