Elon Musk and Grimes Welcome Their First Child Together

Grimes has seemingly welcomed her first child, according to the baby’s father, Elon Musk.

“Mom and baby all good,” Musk, 48, tweeted Monday night in response to a question about the baby — which was nested in the replies to a tweet from Clean Technica about EPA testing for the Tesla Model S.

The tech guru later tweeted that the newborn is a boy, after a fan inquired about the sex, and said that he and his girlfriend had named him X Æ A-12 Musk. He also posted a photo of the baby with some app-generated face tattoos. “Never too young for some ink haha,” he joked.

Grimes, 32, announced her pregnancy in January, later confirming in a March Rolling Stone interview that the Space X head was the father.

Canadian native Grimes, who dropped her fifth album, “Miss Anthropocene,” in February, kept followers breathlessly updated on most aspects of her pregnancy, from sending a digital avatar named “Warnymph” to appear in her stead on a magazine cover to revealing a bespoke recipe for a meal called “sludge” that involves couscous, Vegenaise, sriracha and vegetables.

Grimes described pregnancy as “a pretty crazy sacrifice” to Rolling Stone in March, saying that “it’s sacrificing your body and your freedom.”

“I have spent my whole life avoiding that situation,” she noted, “so it was just a profound commitment.”

The child is Grimes’ first, while Musk has five sons from his previous marriage to author Justine Wilson: twins Griffin and Xavier and triplets Damian, Saxon and Kai.

Page Six exclusively revealed in May 2018 that Grimes and Musk were a couple. They walked the Met Gala red carpet together just a few days later.
