Grimes tried to change the name of her and Elon Musk's baby to just a symbol

You know what comes after “X”...

Celebrities are well-known for giving their children unique names. Already, musician Grimes and Twitter CEO Elon Musk have two children with unique names.

The former couple shares a son named X AE A-XII and a daughter named Exa Dark Sideræl.

But apparently, they had another option for their daughter’s name, however, the government “won’t recognize” the name they wanted for her - a question mark.

So they’ve decided to just nickname her “Y.”

On Thursday, Grimes, whose real name is Claire Boucher, used her Twitter to share a rare photo of her young daughter wearing a matching outfit with her.

In the comments, Grimes told fans “she’s Y now, or ‘Why?’ or just ‘?’ (But the government won’t recognize that). Curiosity, the eternal question, .. and such.”

Grimes said she posted a photo of her daughter because “she’s fairly unrecognizable here since she's channeling Goku or [something].”

Y was (semi) introduced to the world last year when Grimes accidentally revealed she had a second child with Musk via surrogate to Vanity Fair.

Seemingly, the couple wanted to keep their daughter hidden from the world, while their son X often takes a front-and-center stage appearance with his dad.

Grimes told Vanity Fair while she’s “semi-comfortable” with Musk totting around X, she would prefer to keep her daughter out of the public eye.

“The best situation here is me training the girl and [Musk] training the boy,” Grimes said last year.

Like Y’s potential question mark name, the two also tried to give X a name that was denied by California as it violated naming law.

X’s original name was “X Æ A-12” but because California does not allow people to include letters and symbols. So his name was changed to “X Æ A-XII.”
