Elon Musk took to Twitter on Monday to confirm that Grimes and he have welcomed their child into the world.

"Mom & baby all good," Musk wrote when asked for an update on the baby. 

Musk went on to reveal that the child is a boy.

He also said that the boy's name is X Æ A-12. 

The baby is Grimes' first. Musk, who's 48 and the CEO of both Tesla and SpaceX, has five other kids with Justine Wilson, his ex-wife. Grimes, who is 32, has yet to publicly comment about their new arrival. Grimes, real name Claire Elise Boucher, announced that she was pregnant back in January when she posted a photo showing off her baby bump.
