Grimes has educated her fans on how to pronounce the name of her firstborn child.
The Oblivion singer, 32, was rather terse in explaining the unusual moniker in her response to a question asking 'how do you pronounce the baby's name?' on Instagram.
'It's just X, like the letter X. Then A.I. Like how you said the letter A then I,' said the Canadian songstress.
Thanks? Grimes has educated her fans on how to pronounce the name of her firstborn child.
However things weren't so simple according to babydaddy Elon Musk, who told Joe Rogan's podcast on Thursday that the X in the name is spoken 'like the letter' while 'the 'Æ' is pronounced like "ash"'
Musk, 48, announced the birth of his sixth son - his first with singer Grimes - on Tuesday. He shared a photo of himself holding the newborn in his arms, telling fans the baby is called X Æ A-12.
In a two hour long chat released Thursday the billionaire broke down the name before doubling down on his pledge to sell his possessions, telling Rogan he will rent a home. He said: 'What’s the worst that can happen?'
But Musk told Rogan: 'First of all, my partner is the one that, actually, mostly, came up with the name. Yeah, she’s great at names.
When asked to explain the choice Musk replied: 'I mean it’s just X, the letter X. And then, the Æ is, like, pronounced ‘Ash’.
'And then, A-12, A-12 is my contribution. Archangel 12, the precursor to the SR-71, is the coolest plane ever', he added.

Musk has five sons - Griffin, Xavier, Kai, Saxon and Damian - from his previous marriage to Canadian author Justine Wilson.
He has still not explained exactly how to pronounce the name, but added: 'Actually I think it’s better being older and having a kid. I appreciate it more. Babies are awesome.'
Probed on his tweet announcing he will sell all of his possessions Musk said the term billionaire has become a way to target someone. He added: 'I have a bunch of houses, but I don’t spend a lot of time in most of them.
'That doesn’t seem like a good use of assets. Somebody could probably be enjoying those houses and get better use of them than me.'
He confirmed he would rent a property, rather than own one.
The tech entrepreneur, who according to Forbes is worth more than $38 billion, tweeted that he intends to sell 'almost all physical possessions.'
'Will own no house,' Musk tweeted. He then remarked: 'Just one stipulation on sale: I own Gene Wilder's old house. It cannot be torn down or lose any its soul.'
Musk also waded into the coronavirus lockdown debate, telling Rogan 'we should treasure' freedom and democracy and 'not give up our liberties too easily'. He added: 'I think we probably did that.'
'My opinion is, if somebody wants to stay home, they should stay home, and if somebody does not want to stay home, they should not be compelled to stay home.
'That’s my opinion. And if somebody doesn’t like that, well, that’s my opinion', he added.
And he discussed work with brain function via his company, Neuralink, telling Rogan: 'We would basically take out a chunk of your skill and put the Neuralink device in there.
'You insert the electrode threads very carefully in the brain and then you stitch it. It would interface anywhere in the brain and it could restore your eyesight and limb functionalities.
'If you have severe epilepsy, it could detect it in real-time and stop it from occurring. There are a whole list of injuries — for example, if a person has a stroke, that could also be fixed if you lose muscle control.'

In November 2013, Musk purchased a three-quarter-acre Bel Air home for $6.75 million. That property once belonged to Wilder, the late Willy Wonka actor who died in 2016. Musk has since turned the property into a private school.
It is one of six that Musk bought within walking distance of each other.
Musk also purchased a seventh home near Tesla headquarters in Northern California.
In total, he has spent more than $100million for seven properties since 2012, according to The Wall Street Journal.
