Elon Musk & Grimes Welcome 2nd Baby Together!

Elon Musk and Grimes have welcomed their second baby together — and you won’t believe what they named the little tot!

In a cover story for Vanity Fair’s April 2022 issue, the musician revealed that she and the Tesla CEO welcomed a daughter in December 2021 via surrogate.

Though their newborn is named Exa Dark Sideræl, they have nicknamed her Y!

The nickname is appropriate given that the couple’s first child together, a boy born in May 2020, is named X Æ A-12.

With regard to her daughter’s unique moniker, Grimes explained that Exa refers to a supercomputing term, exaFLOPS, while Dark represents “the unknown.”

“People fear it, but truly it’s the absence of photons. Dark matter is the beautiful mystery of our universe,” she said.

Sideræl, pronounced “sigh-deer-ee-el,” is “a more elven” spelling of ”sidereal,” which Grimes defines as “the true time of the universe, star time, deep space time, not our relative earth time.”

The name is also a nod to her favorite “Lord of the Rings” character, Galadriel, who “chooses to abdicate the ring.”

Though Grimes reveals she was “fighting” to name her daughter Odysseus Musk, because “A girl named Odysseus is my dream,” she and Musk settled on Exa Dark Sideræl.

At the time of the interview, Grimes told the magazine that she and Musk are back together following reports that they split up in September 2021.

“There’s no real word for it,” she said. “I would probably refer to him as my boyfriend, but we’re very fluid. We live in separate houses. We’re best friends. We see each other all the time… We just have our own thing going on, and I don’t expect other people to understand it.”

She added, “This is the best it’s ever been... We just need to be free.”

However, after the interview was published, Grimes clarified on Twitter that she and Musk have “broken up *again*.”

Despite this, Grimes told Vanity Fair that the two plan to have more children.

“We’ve always wanted at least three or four.”
