Billionaire Elon Musk’s girlfriend explains the special meaning behind her son’s unique “weird” name.
Elon Musk and his girlfriend, the artist and musician known as Grimes, have never shied away from making headlines, whether for Musk’s groundbreaking ventures or Grimes’ avant-garde artistry. But when they announced the birth of their son and revealed his unique name—X Æ A-Xii—it sparked widespread curiosity and confusion. Now, Grimes has stepped forward to explain the special meaning behind their son’s unconventional name, shedding light on the thought process that went into it.
In an interview, Grimes described the name as a reflection of their shared passions and personalities, combining elements of technology, art, and symbolism. “It’s more than just a name,” she said. “It represents a nod to our interests and the things we value in life—science, creativity, individuality, and the unknown.”
Breaking down the components of the name, Grimes explained that “X” represents the unknown variable, a symbol often used in mathematics and science to signify something undefined yet full of potential. It’s a tribute to the boundless curiosity and exploration that both she and Musk hold dear. “X is the essence of possibility,” she added.
The “Æ” portion of the name, she explained, has both aesthetic and linguistic significance. Pronounced “Ash,” it is an old English ligature that also appears in several other languages. Grimes said the symbol resonates with her as an artist because of its beauty and its connection to language, history, and storytelling. For Musk, a known lover of engineering and design, it carries a sleek, futuristic vibe.
“A-Xii,” the final component, holds a deeper, more personal meaning for the couple. The “A” stands for “Archangel,” the name of Grimes’ favorite song by the electronic artist Burial. The “Xii” (12 in Roman numerals) is a nod to the SR-71 Blackbird, the fastest manned aircraft ever built and one of Musk’s favorite technological marvels. The couple views the aircraft as a symbol of innovation and pushing boundaries, concepts that resonate with their shared vision for the future.
Grimes emphasized that while the name might seem unusual to others, it feels perfectly natural to them. “To us, it’s a poetic and meaningful name that reflects our son’s potential to grow into someone who can challenge norms and redefine what’s possible,” she said. “We didn’t want to give him a name that just blends in—we wanted something that celebrates individuality and our family’s love for exploring new frontiers.”
Reactions to the name have ranged from admiration to amusement, with many fans praising the couple’s creativity while others jokingly questioned how to pronounce it. For their part, Musk and Grimes seem unbothered by the commentary. Musk himself joked in a tweet, “It’s pronounced ‘Ex Ash A Twelve,’ but honestly, we just call him X.”
As unconventional as the name might be, it’s clear that X Æ A-Xii represents more than just a label—it’s a reflection of his parents’ shared vision for the world, blending their love of science, art, and innovation into something uniquely their own. And for a child born to two of the most forward-thinking minds of our time, it feels like a fitting start to a life filled with possibility.

Elon Musk and Grimes had Twitter in a tizzy this week when they announced that they had named their child, X Æ A-12.
The new mom took to Twitter to explain the meaning behind the unique moniker, and Musk shared how to pronounce the name while on The Joe Rogan Experience podcast.
The billionaire technology entrepreneur revealed that his son was born on May 4, aka May the Fourth Be With You, which Rogan pointed out was “the perfect day” for Musk, a Star Wars fan.
Rogan outright asked how to pronounce X Æ A-12, which garnered a laugh from Musk. “Is it a placeholder?” the podcast host inquired.
“Well, first of all, it was my partner [Grimes] who actually mostly came up with the name,” Musk shared. “She’s brilliant.”
As for how to say the name, the Tesla founder explained, “So, it’s just X, the letter x, and then the Æ is pronounced Ash.”
Musk’s contribution to the name is A-12, which is an ode to the Archangel 12, the “precursor to SR-71, the coolest plane ever.”
So according to Musk, his son’s name is X Ash Archangel Twelve. “It’s great,” he said proudly.
At 48, this is Musk’s sixth child and his first with 32-year-old Grimes. “I think it’s better being older and having a kid,” he said. “I appreciate it more. Babies are awesome.”
Earlier this week, Grimes attempted to share her newborn son’s name and offer an explanation, but flubbed the part of the little one’s name that Musk came up with.
The singer said that A-12 refers to an aircraft which is the “precursor to SR-17 (our favorite aircraft). No weapons, no defenses, just speed. Great in battle, but non-violent.”
Musk later corrected her on Twitter, writing: “SR-71, but yes.”
Grimes replied to the father of her child, “I am recovering from surgery and barely alive so may my typos b forgiven but, damnit. That was meant to be profound 🦔.”
While neither Grimes nor Musk have confirmed where she gave birth, many fans believe she had the baby in California. As numerous media outlets have reported, if she did in fact give birth there, the name will not be accepted by the state.
In California, you are only to use the 26 letters in the alphabet for a baby name, and an apostrophe if needed. Numbers, Roman numerals, emojis, accents or other symbols are not acceptable.
Just prior to welcoming another child, Musk announced that he was getting rid of almost all of his worldly possessions.
“I’m slightly sad about it actually,” he admitted to Rogan on his podcast. “I think possessions kind of weigh you down. They’re kind of an attack factor. They’ll say, ‘Hey, billionaire, you got a lot of stuff.’ Well, now I don’t have the stuff. Now what are you going to do?”
Musk will be keeping a few Teslas for “research” purposes, as well as some clothes and possessions with personal importance to him. He will, however, be selling all of his homes and renting a place instead.
As for Grimes, prior to giving birth, she put her baby bump on display for Vogue Italia and shared what it was like being pregnant amid the coronavirus pandemic.
“It is certainly very demanding to be pregnant in the middle of a pandemic. It’s hard not to be able to see friends and family,” Grimes admitted. “A friend of mine recently died and it was a nightmare not being able to be close to her loved ones. It won’t be easy in the hospital, I don’t go into details but I feel very empathetic with those who are going through this phase. And I trust what the maternity wards are doing to manage the situation, I have great respect for the work of the doctors.”
Singer Ciara is also pregnant while in quarantine and shared with ET how that has been for her. Check out our exclusive interview.
