LOS ANGELES — Elon Musk and his girlfriend Grimes welcomed their first child into the world.
Tesla and SpaceX CEO Musk confirmed the news in a tweet on Tuesday night. He opened up about the exciting news on Twitter when fans asked for an update on the baby after he said 32-year-old Grimes was due on Monday.
Musk later tweeted out that the couple named their son X Æ A-12 Musk.
Grimes later tweeted the meaning of her son's name.
"•X, the unknown variable
•Æ, my elven spelling of Ai (love &/or Artificial intelligence)
•A-12 = precursor to SR-17 (our favorite aircraft). No weapons, no defenses, just speed. Great in battle, but non-violent
+ (A=Archangel, my favorite song) (metal rat)"
Musk shared two photos of the baby, one with an Instagram filter over the infant's face so it looked like he had tattoos and one with the baby in Musk's arm.
Grimes, the “So Heavy I Fell Through the Earth” singer, first confirmed she was pregnant in a post on Instagram in early January.
She wrote in the photo's caption, "how do y’all cope with working and having a baby?? I’m sorry I haven’t been promoting my album properly or on social media more. This whole thing has been a bit of an ordeal."
She added: "Had some complications early on, a decent second trimester but starting to hurt everywhere at 25 wksz. What were yalls experience w this stuff like?"
Musk and Grimes have been a couple since publicly walking the red carpet at the Met Gala together in 2018.
