Elon Musk and Grimes have secretly welcomed their second child to the world, with yet another unique name.
Their first baby boy was born in May 2020 and was called 'X Æ A-12', which she pronounces 'X A.I. Archangel,' or X for short.
Grimes - who's real name is Claire Elise Boucher - used a surrogate this time, which essentially allowed them to keep their daughter a secret... until now.

It also appears that the pair are now back together after seemingly breaking up last year. Grimes now refers to Musk as her 'boyfriend'. She said: “There’s no real word for it.
“I would probably refer to him as my boyfriend, but we’re very fluid.
"We live in separate houses. We’re best friends. We see each other all the time…. We just have our own thing going on, and I don’t expect other people to understand it.”
She added: “This is the best it’s ever been.... We just need to be free.
Speaking to Vanity Fair, Grimes revealed that her newborn baby girl is called 'Exa Dark Sideræl Musk', otherwise known as 'Y'.

Apparently she is named after the supercomputing term 'exaFLOPS', which is the ability to perform one quintillion floating-point operations per second.
Not going to pretend like I know what that means.
'Dark' refers to 'the unknown', apparently.
Grimes said: "People fear it but truly it’s the absence of photons. Dark matter is the beautiful mystery of our universe."
Grimes also revealed that during the last month of pregnancy with X, she found it hard to walk.

She said: "He was pressing on my nerves, so I kept collapsing.
“I took a few steps and collapsed. It was kind of scary, because you don’t want to fall a lot when you’re eight months pregnant.
"So I would just crawl to the bathroom and crawl back or whatever.
"Like, I hemorrhaged. It was scary.”

Last year, Musk and Grimes announced their (semi-)separation, with Musk saying in a statement to Page Six: "We are semi-separated but still love each other, see each other frequently and are on great terms.
"It's mostly that my work at SpaceX and Tesla requires me to be primarily in Texas or traveling overseas and her work is primarily in LA.
"She's staying with me now and Baby X is in the adjacent room."
Well, it looks like they're semi back together again now, and I'm sure this won't be the last we hear from them.
