Grimes is sharing a new update on her little girl.

The singer and mom of two — who shares daughter Exa Dark Sideræl, 15 months, and son X Æ A-12, 2½, with ex Elon Musk — shared new side-by-side photos of her and her toddler on Twitter Thursday.

Both mom and daughter were dressed in red onesies in the photo, with Grimes (born Claire Boucher), 31, sporting green tips at the end of her yellow-blonde hair and the toddler donning a similar look in her little tufts of hair.

"Normally we [don't] post her for her privacy, but she's fairly unrecognizable here since shes channeling Goku or smthn," she tweeted as a follow-up to the photo set.

In another tweet, she commented on her toddler's name, writing, "She's Y now, or 'Why?' or just '?'" calling the name "curiosity, the eternal question, .. and such."

Grimes also acknowledged that the change isn't official because the "government won't recognize that."

In September, Grimes shared photos of her daughter listening to music and playing with a copy of The Birth of Tragedy by German philosopher Friedrich Nietzsche.

"My daughter is dancing to techno over this copy of the birth of tragedy by Nietzsche - what a queen," she tweeted alongside the shot of the then-9-month-old leaning on a bench in a black onesie with a pink bow headband in her blonde hair.


Grimes first told Vanity Fair that she and Musk welcomed a daughter in December 2021 via surrogate in a cover story for the magazine's April 2022 issue.

The singer explained her daughter's unique name to the outlet, telling Vanity Fair that Exa refers to a supercomputing term, exaFLOPS, while Dark represents "the unknown." She explained, "People fear it but truly it's the absence of photons. Dark matter is the beautiful mystery of our universe."

At the time, she told the outlet that they plan to have more children too: "We've always wanted at least three or four."

In addition to his two children with Grimes, Musk shares 19-year-old twins Vivian Jenna Wilson and Griffin Musk, along with triplets Kai, Damian, and Sax Musk, who were born in 2006, with his first wife, Justine Wilson. The two had another son, Nevada Musk, who died at 10 weeks.
