Before landing on Blue Ivy Carter, Jay-Z and Beyoncé were actually crazy in love with another name.

"It was supposed to be Brooklyn," the "Forever Young" rapper revealed in an Oct. 27 interview with CBS Mornings, a connection to his beloved hometown. "That was the name we had in theory. But when we got the little sonograms, you know, they're super small and we were calling her Blueberry. It was like a nickname. And for nine months we're like, 'Look at little Blueberry.'"

So it was on to the next one as far as they were concerned when it came to a moniker for their daughter, now 11.

"It was natural," the Emmy winner, who also shares twins Rumi and Sir Carter, 6, with the "Crazy in Love" singer, continued. "We just took the Berry off and just called her Blue."

And, of course, the rest is history. 

As for what that history entails? Well, as concertgoers of the Beyoncé's Renaissance World Tour witnessed this year, Blue Ivy graced the stage alongside her mom to slay a few routines for the first time—an experience her dad couldn't be prouder to see.

"I still get goosebumps seeing her walk on stage," he shared. "Because Blue's been born into this world, she's been born into a life she didn't ask for. Since she was born, she's been in scrutiny and everyone has an opinion. Even [as] a little girl, how she keeps her hair. So for her to be on that stage and reclaim her power, and the song is called ‘My Power,' and it's just—you can't write a better script."

And while the musician knows first-hand that 99 problems can easily happen as a performer, Blue gave it all her energy and didn't look back.

"I know how nervous she was," he said. "I know how frightened she was. And she wanted to do it. She wanted to do it the first night, and we were like, ‘Okay, if it's something you want to do, you can't just go out there. You gotta go work with the dancers and go work.' And she worked every day."

But Blue isn't the only celeb kid with a name that's simply irreplaceable. Keep reading for even more unique names.

As Gwyneth Paltrow explained to Oprah Winfrey, her daughter's unforgettable name was actually picked by Chris Martin: "When we were first pregnant, her daddy said, 'If it's a girl I think her name should be Apple'...It sounded so sweet, and it conjured such a lovely picture for me, you know. Apples are so sweet and they're wholesome, and it's biblical."

"Exa is a reference to the supercomputing term exaFLOPS (the ability to perform 1 quintillion floating-point operations per second)," she said. "Dark, meanwhile, is 'the unknown. People fear it but truly it's the absence of photons. Dark matter is the beautiful mystery of our universe.'"

Switching over to roman numerals, the parents agreed to spell his name, X Æ A-Xii.

"X, the unknown variable," Grimes explained on Twitter. "Æ, my elven spelling of Ai (love &/or Artificial intelligence) A-12 = precursor to SR-17 (our favorite aircraft). No weapons, no defenses, just speed. Great in battle, but non-violent."

Grimes continued, "A=Archangel, my favorite song" with an accompanying a rat and sword emoji. "Metal rat."
