Tesla founder Elon Musk and musician Claire Boucher, stage name Grimes, welcomed their first child on Monday.
“A few hours away!” Musk responded on Twitter before sharing the news that the baby boy had been born. “Mom & baby all good,” he added a few hours later.
The baby is Grimes’ first child, and joins Musk’s five sons from his marriage to ex-wife, author Justine Wilson.
The baby’s name
Their chosen name for their son, however, has raised eyebrows.
Memes speculating on the weird baby name the unconventional couple would likely choose for their child have been floating around the internet ever since the pregnancy was announced.
And Musk certainly didn’t disappoint, announcing his son’s name on Twitter as “X Æ A-12.”
It’s not entirely clear if Musk was joking; his Twitter page is filled with absurdist, surreal humor, in-between regular Tesla and SpaceX updates.
