Grimes doesn't "identify" with the word mama or mother — so her son calls her by her real name.
The musician - whose real name is Claire Elise Boucher - welcomed son X Æ A-12 into the world with her partner Elon Musk back in May 2020, but her son doesn't call her mother and instead chooses to refer to her by her name Claire.
She explained how having a baby was "a big rebirth" for her but she has a "distaste" for the word mother.
"I think having a baby was a big rebirth for me artistically. Being a mother feels weird for me to say," she told Vogue magazine.
"X says Claire, but he doesn’t say 'mama'… like, maybe he can sense my distaste for the word 'mother.'
"I don’t even know why I have a distaste for it, I respect it ... I just can't identify with it, weirdly."
Grimes had previously explained how the couple came up with the unusual moniker for their child.
"X, the unknown variable," ️Grimes began in her post.
She continued: "Æ, my elven spelling of Ai (love &/or Artificial intelligence)."
"A-12 = precursor to SR-17 (our favorite aircraft). No weapons, no defences, just speed. Great in battle, but non-violent.
"A=Archangel, my favorite song."
However, the pair have differing ideas on how to pronounce the name.
"it’s just X, like the letter X. Then A.I. Like how you said the letter A then I," Grimes responded to one fan.
And when he was asked how it was pronounced, he added: "I mean it's just X, the letter X, and the 'Æ' is pronounced, 'Ash.'"
Elon and Grimes, however, faced a little trouble making the name official when they attempted to register the tot's name.

According to TMZ, a supervisor at the Department of Public Health Vital Records Office said they would not be able to legally put the name on the birth certificate because Californian law doesn't permit symbols or numbers.
They went on to change the baby's name to X AE A-XII (with no special characters and numbers) followed up with the last name 'Musk'.
When she was pregnant, Grimes admitted she didn't see people's fascination with her relationship with Elon.
"I just did not understand what I was getting into at all. Not that I’m mad about it. I just didn’t think it would be a thing. The s**t that’s happened with my boyfriend this year has overwritten so much of my life’s work," she told Rolling Stone magazine.Read More Read More
