# A Reporter Heard an Infant Screaming and It Turned Out Elon Musk Had a Secret Baby with Grimes

## Exa Dark Sideræl

We certainly didn't see this one coming.

Acclaimed musician Claire "Grimes" Boucher and SpaceX CEO Elon Musk had a second child with the help of a surrogate mother in December, according to an unhinged new [*Vanity Fair* interview](<https://www.vanityfair.com/style/2022/03/grimes-cover-story-on-music-and-mars>).

Just like her first child with Musk, Grimes' new daughter has an eyebrow-raising name: Exa Dark Sideræl Musk, or "Y" for short.

Exa Dark Sideræl is Musk's first daughter, after having seven sons. The last one — X — was also with Grimes.

It's a pretty wild interview to say the least. In fact, Grimes didn't even lead the interview with the news she had another child with Musk.

"Full-blown infant screams upstairs" gave Y's existence away.

"I'm not at liberty to speak on these things," Grimes told *Vanity Fair* at first, clearly trying to move the conversation in a different direction.

## X and Y

The couple [had their first child](<https://futurism.com/the-byte/elon-musk-grimes-baby-name-claim>) together in May 2020, naming it "X Æ A-12 Musk" — truly a mouthful — and [later changed](<https://futurism.com/the-byte/elon-musk-grimes-updated-babys-name>) it to "X Æ A-Xii," or "X" for short.

After dating for three years, the couple [broke up](<https://futurism.com/the-byte/elon-musk-grimes-broke-up>) in September 2021.

"We are semi-separated but still love each other, see each other frequently and are on great terms," Musk [told gossip outlet *Page Six*](<https://pagesix.com/2021/09/24/elon-musk-and-grimes-break-up-after-three-years-together/>) at the time.

Things are still a little complicated between the two. And don't forget that Musk is [reportedly dating someone new](<https://futurism.com/the-byte/elon-musk-new-girlfriend>).

"I would probably refer to him as my boyfriend, but we’re very fluid," Grimes told *Vanity Fair* more recently. "We live in separate houses. We’re best friends. We see each other all the time."

## Author
I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida.
