Grimes unintentionally announced the birth of her second child with Tesla co-founder and CEO Elon Musk via surrogate.In an exclusive interview with Vanity Fair, Grimes said the baby girl, named Exa Dark Sideræl Musk (pronounced sigh-deer-ee-el), was born in December.
The couple also refer to their daughter as “Y.”The new child’s name is complex, with Exa being a reference to exaFLOPS (or, the ability of supercomputers to perform 1 quintillion floating-point operations per second).
Dark refers to the unknown and Sideræl is a “more elven” spelling of sidereal, the timekeeping system used by astronomers to locate celestial objects.
Sideræl is also a reference to Grimes’ favourite Lord of the Rings character, Galadriel.
