Grimes Announces Birth of Second Child With Elon Musk Via Surrogate

etonline.com:

Grimes has welcomed her second child with Elon Musk. The 33-year-old musician, whose real name is Claire Elise Boucher, shared the news in a new cover story.

During the interview, Grimes is hesitant at first to discuss expanding her family, saying, «I’m not at liberty to speak on these things.

Whatever is going on with family stuff, I just feel like kids need to stay out of it, and X is just out there.» However, she then shares that she and Musk, 50, secretly welcomed a daughter they call Y via surrogate in December. “Her full name is Exa Dark Sideræl Musk," Grimes tells the magazine.

As for the meaning behind the unique moniker, Grimes shares that Exa is a reference to the supercomputing term exaFLOPS (the ability to perform 1 quintillion floating-point operations per second), while Dark represents «the unknown.»«People fear it but truly it’s the absence of photons,» Grimes says. «Dark matter is the beautiful mystery of our universe.” As for Sideræl — pronounced sigh-deer-ee-el — Grimes describes it as „a more elven“ spelling of „sidereal,“ which means “the true time of the universe, star time, deep space time, not our relative earth time.” It’s also a nod to Grimes' favorite Lord of the Rings character, Galadriel.
