Elon Musk and his ex-girlfriend Grimes have secretly welcomed their second child.
The singer confirmed that she and the Tesla founder had become parents again in an interview with the new issue of Vanity Fair magazine.
Grimes – who also shares 22-month-old son X Æ A-Xii, with Elon – confirmed the couple welcomed a daughter in December 2021 via surrogate.
The baby’s name is Exa Dark Sideræl, although the couple nicknamed her Y.
Grimes explained his daughter’s unique name by describing how Exa refers to a supercomputing term, exaFLOPS, while Dark Universe stands for “the unknown.”
She said: “People fear it, but it’s really the absence of photons. Dark matter is the beautiful mystery of our universe.”
Grimes described Sideræl as the “more Elvish” spelling of “sidereal” – which she defined as “true universe time, star time, deep space time, not our relative earth time “.

The name is also a nod to the “Lord of the Rings” star’s favorite character, Galadriel.
Despite splitting last September, Grimes revealed she still considers Musk her “boyfriend” but describes their relationship as “very fluid”.
The pop star, whose real name is Claire Boucher, said: “There’s no real word for it. I would probably call him 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 that.
“It’s the best it’s ever been… We just need to be free.”
Grimes also hinted that she and Elon wanted to have more children.
She said, “We always wanted at least three or four.”
