In a recent interview with Vanity Fair, musician Grimes revealed that she and her longtime partner, Tesla CEO Elon Musk, have welcomed their second child via surrogate.
The two made news when they announced their first child, X Æ A-12 Musk (also known as "Baby X"), and were largely made fun of online for the unusual name they chose. Now, Grimes has revealed the name of their daughter, and it's just as experimental as her brother's. The singer shares,
"Her full name is Exa Dark Sideræl Musk. Exa is a reference to the supercomputing term exaFLOPS (the ability to perform 1 quintillion floating-point operations per second). Dark, meanwhile, is ‘the unknown'. People fear it but truly it's the absence of photons. Dark matter is the beautiful mystery of our universe.'"
As for Sideræl (pronounced "sigh-deer-ee-el"), Grimes says it's a reference to her favorite Lord of the Rings character, Galadriel, who "chooses to abdicate the ring."
"It's the true time of the universe, star time, deep space time, not our relative earth time."
Back in September, Musk confirmed that he and Grimes had split after three years of dating. He stated in an interview at the time,
"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."
Grimes says their relationship now is unconventional, but that they've never been happier.
"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. This is the best it's ever been. We just need to be free."
