Elon Musk and Grimes Welcomed Their Third Child, Techno Mechanicus, According to New Biography

Elon Musk and Grimes have privately welcomed a third child named Techno Mechanicus, according to a new biography about the business magnate.

The biography, written by Walter Isaacson, revealed that Musk and Grimes had Techno, whose nickname is Tau, and kept their life extremely private.

With the addition of Mechanicus, Musk and Grimes welcomed their first child, X Æ A-Xii, in May 2020. In an interview with Vanity Fair in 2022, the singer revealed they also had a daughter named Exa Dark Sideræl Musk through a surrogate in December 2021.

The Tesla CEO recently had twins in November 2021 with Neuralink executive Shivon Zilis, which Grimes didn't know about. Zilis had the children after Musk donated his sperm because, as Isaacson wrote in his book, "the kids would be genetically his."

"He really wants smart people to have kids," Zilis says in the book about Musk, who now has 10 children with three different women.

Earlier this week, Grimes hopped on Twitter and had some words for Musk and Zilis about not being able to see her son and how their "situation" has caused a rift in her family.

"Tell Shivon to unblock me and tell Elon to let me see my son or plz respond to my lawyer," Grimes wrote in a since-deleted tweet. "I have never even been allowed to see a photo of these children until this moment, despite the situation utterly ripping my family apart."

Elon Musk and Grimes went public with their relationship at the 2018 Met Gala. However, in 2021, the two announced they had "semi-separated."
