Elon Musk Kids

As far as Elon and Grimes are concerned, she says they've split since the article was published, tweeting, "Me and E have broken up *again* since the writing of this article haha, but he’s my best friend and the love of my life, and my life and art are forever dedicated to The Mission now, I think Devin wrote that part of the story rly well. Sique - peace out"

Elon Musk and Grimes have a second child ... a baby girl who they've managed to keep under wraps for several months, but now they're revealing the big secret!

Grimes says their daughter was born back in December via surrogate and her name, as you'd expect, is totally unique -- Exa Dark Siderael. But, they're calling her Y, for short. Remember, they have a 22-month old son X Æ A-12, who goes by X.

Grimes dropped the baby news to Vanity Fair and addressed the elephant in the room ... namely, that we all thought she and Elon broke up back in September.

The singer says they've since reconciled, in their own way. She says, "I would probably refer to him as my boyfriend, but we're very fluid."

Baby X was born back in May 2020, and prior to that Musk had 5 sons -- a set of twins and a set of triplets -- from his previous marriage to author Justine Wilson. X was Grimes' first kid.

Since his birth, baby X has gotten the spotlight quite a few times ... even being the highlight in dad's viral zoom presentation back in November 2021.

She says the family is very happy, marking this as the best their relationship has ever been. They also plan on having more kids, but obviously, we won't expect them to be public about it.

Congrats to the happy couple, and welcome Y!

Elon Musk can read a room -- getting ahead of potential groans and eye-rolls over him being named TIME's Person of the Year by sprinkling some adorableness on the ceremony ... courtesy of his kid.

The Tesla and SpaceX chief popped in for a Q&A Monday night in NYC, not too long after it was announced he was TIME's number 1 person for the entirety of 2021. His entrance turned out to be a big fat father-son love fest, 'cause EM trotted out X Æ A-12 for the sit-down.

It's pretty hilarious ... as soon as Elon comes into the room with X in his arm, just about everyone lets out the expected "awwwws" that come in the presence of any toddler.

X's appearance definitely softened any would-be tension that might've existed among the reporters and spectators there ... 'cause, as you may have read or heard, not everyone was all that thrilled with Elon getting the huge honor.

Nobody probably would've made a scene or anything, but bringing X along for the ride is definitely a good PR move on Dad's part.

As for the actual interview itself, Elon talked about a lot of stuff -- including whether he considered cars or rockets more important, and whether he'd ever get his ass up into space like his billionaire rival, Jeff Bezos.

Meanwhile, young X was on his best behavior (for the most part) ... not really fussing too much, and listening to his pops chat it up in what was almost certainly a new environment for him.

Elon Musk's son upstaged his dad's rocket re-entry during a zoom presentation, and the kid made something clear ... he was not happy to get yanked from the action!

X AE A-Xii -- government name -- was on the lap of his 50-year-old pops during a conference about Elon's reusable rockets -- a feat even NASA has not been able to duplicate.

The boy was happily babbling in a zoom box as the folks at the conference had a choice ... focus on the rocket or the tyke. We're guessing the kid gave the rocket a run for its money.

Once the booster hit solid ground, someone opened the door and Elon's son made a very unhappy exit. You could hear him cry even after the door closed. Elon was slightly amused and then went on with the show.

Musk went on to tell those present at the National Academy of Sciences, Engineering and Medicine about his Starship spacecraft.

It's rare we see Elon interact this way ... he said after X was born, "Babies are just eating and pooping machines, you know. Right now there's not much I can do," adding Grimes, the baby's mom, is essentially the primary caregiver.

Elon and Grimes are no longer together, but they clearly share a love for X ... gotta say, the kid's adorable.

Elon Musk still doesn't seem to know what the heck's in store for his big debut on "Saturday Night Live" ... and he's even resorted to asking photogs about what skits he should do.

The Tesla CEO is in NYC Tuesday, days ahead of taking the stage at NBC Studios -- where he'll be hosting 'SNL' -- and the moment he showed his face in the streets he was swarmed ... mostly by autograph seekers who shoved dozens of Sharpies and photos in his face.

Of course, the one thing on everyone's mind is what he's got in store for Saturday's show. Check it out -- sounds like Elon still isn't entirely sure, but hey ... it's only Tuesday.

He regurgitated some ideas he was spitballing on Twitter over the weekend ... including Baby Shark Tank and a Dogecoin riff. Doesn't seem like he's touched base with 'SNL' staff quite yet.

BTW, Elon's appearance in the Big Apple is a family affair ... he touched down at Teterboro Airport in New Jersey Monday night with none other this his partner, Grimes, and their baby boy, X Æ A-12, in tow.

EM was handling cradling duties as they exited to a waiting vehicle, and he seemed to be doing a damn good job at it too. Meaning ... he didn't drop the kid!!!

Elon Musk is showing off his pride and joy -- no, not the Falcon 9 -- little baby A-12 ... but he's also making it clear the kid's following in big footsteps, so he better get his spoon skills up!

The Tesla and SpaceX honcho posted a pic of himself cradling X Æ A-Xii, (it's pronounced X Ash A12) ... adorable, right? But, Elon's caption -- in German for some reason -- translates to "The baby cannot use a spoon yet."

We're pretty sure Papa Musk is joking because A-12 isn't even 3-months-old yet!!! While we have no doubt Elon sets a high bar for his kids, there are limits ... even for the son of Musk.

Elon Musk and Grimes really followed through with their outta this world baby name ... but they had to play a little ball to comply with California law.

According to the newborn's birth certificate, obtained by TMZ, Elon and Grimes named their first child, X AE A-XII Musk. Seriously.

Mom and Dad had to get a little creative -- as if the kid's name wasn't clever enough -- to make their tyke all legal and stuff. As you know ... Elon and Grimes' baby boy was born last month, and they wanted to name him X Æ A-12 Musk.

As it turns out, the aeronautic name didn't fly in Cali, where birth names must be limited to the English alphabet -- no numbers or special signs.

The result, as you can see, is a first name X, middle name AE A-XII ... and last name Musk. See? Roman numerals ARE good for something besides Super Bowls!

If ya missed it, here's a breakdown on little X's handle: X stands for an unknown variable, AE is like artificial intelligence or AI, and A-XII is the name of a 1960s USAF spy plane.

The pronunciation goes like this ... X like the letter, AE is pronounced "Ash" and then your standard A-12. As in, X-ash-A12. Duh!

That'll be fun on the playground.

Elon Musk and Grimes can call their newborn baby son whatever they want, but on his birth certificate, X Æ A-12 is a no-go ... TMZ has learned.

According to a supervisor at the Department of Public Health Vital Records Office in Los Angeles -- where the baby is believed to have been born -- it is against California law to include numbers or symbols in a name.

The law states names must only include the 26 letters of the English alphabet ... obviously, the name Musk and Grimes are claiming for their boy does not meet that criteria.

As we reported ... the Tesla honcho revealed the news of the baby's birth and photos via a series of Twitter replies Monday, along with the odd name choice.

Grimes later explained the name was inspired by the A-12 plane -- a precursor to the couple's favorite aircraft, which was a CIA spy plane used during the Cold War -- among other interesting things.

That might all be moot now, though, as the kid's legal name will have to be something else ... unless they just shorten it to A for Archangel, or go with "metal rat."

Ya never know with these 2.

Elon Musk is having himself quite a week -- he put 2 homes on the market, he's potentially shooting a movie in space with Tom Cruise, and oh yeah ... he had a baby with his girlfriend, Grimes.

The Tesla honcho revealed the news on Twitter Monday evening by first replying to a tweet by saying the birth was a few hours away, then following it up by tweeting ... "Mom & baby all good."

Soon after, he responded to a request for a baby pic with a shot of him holding his newborn son ... which he claims shall be named "X Æ A-12 Musk." He also posted one later of his kid with some "savage" face tattoos via social media filters.

The baby is the first for Grimes and the sixth for Musk. He has five sons -- a set of twins and a set of triplets -- from his previous marriage to author Justine Wilson.

As we've reported ... there hasn't been a dull moment with Elon the past week or so, especially on Twitter. He's been pushing to "free America now" amid the coronavirus pandemic, and has vowed to sell "almost all physical possessions" and not own a house.

He seems to be walking the walk too ... because he just put a pair of his Bel-Air mansions on the market this weekend.

As for that movie in space with Tom Cruise ... the actor and Musk's Space X are working with NASA on an action-adventure flick that would actually be shot in outer space, according to a Deadline report.

It's apparently in the early stages of development ... just like Musk's newborn son.

Like we said -- never a dull moment.
