Grimes and Elon Musk have secretly welcomed a third baby together, and his name is just as unique as his big brother and sister’s.

According to a new biography on the Tesla CEO’s life, the couple have had a third baby – a little boy, named Techno Mechanicus. The couple also share another son named X Æ A-XII, or ‘X’, who was born on May 4, 2020.

They also welcomed a daughter via surrogate in December 2021, named Exa Dark Sideræl, who is nicknamed ‘Y’. The couple went their separate ways in 2021 after three years together.

According to The New York Times’ review of the biography by journalist Walter Isaason, their third child goes by the nickname ‘Tau’.

Grimes, whose real name is Claire Boucher, revealed that she and Elon secretly welcomed their daughter via surrogate in December 2021, during an interview with Vanity Fair. The couple had been keen to keep their new arrival out of the limelight, until the baby was overheard crying during the interview.

“I don’t know. I don’t know what I was thinking,” Grimes said after trying to conceal her bundle of joy.

The 35-year-old revealed her daughter’s name is Exa Dark Sideræl, but they call her Y. Her older brother’s name is pronounced X A.I. Archangel, but he’s known as X.

While Elon and Grimes separated in 2021 after three years together, it appears they did get back together. Kind of.

“I would probably refer to him as my boyfriend, but we’re very fluid,” Grimes told Vanity Fair. “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.

“This is the best it’s ever been. We just need to be free.”

Elon has six sons with his former wife Justine Wilson: twins Griffin and Xavier, 18, and triplets Damian, Saxon and Kai, 17. The pair’s first son, Nevada Alexander, died from sudden infant death syndrome at 10 weeks old.

It’s also believed Elon secretly welcomed a set of twins, son Strider and daughter Azure, with Shivon Zilis in November 2021.

  • Sounds like Elon Musk and Grimes are well suited. I’d like to say something nice about what they have named their kids but I can’t.


  • Don’t think they got the memo that suggests you name your kids an actual name. I suppose it’ll help them stand out.


  • Oh wow, some people go to extreme lengths to have unique names for their children. I dont think they give any thought to how it will affect the children growing up. Although I expect loads of money will make the pain bearable


  • If they’re happy it’s not really our business.


  • Amazing..congrats to the parents and siblings


  • I do know other people that live this way and it works for them.


  • Congratulations to them both… interesting name choice…


  • Congratulations to them both. If they want to live separately but stay friends the children won’t really miss out too much. I’m not keen on the names but that’s up to them.


  • I do feel sorry for the kids with those names. They’ll be a real burden.


  • They keep things quiet, as they can. I remember when they had their first child, so I can’t believe they now have 3.


  • No idea who these people are, but congrats to this family


  • Why do parents call there kids odd names? Those poor kids.


  • All I want to say is thank goodness people can change their names if they wish. Best of luck to you “children” .


  • What utterly ridiculous names!


  • The names are ridiculous. Poor kids.
