On September 12, a new biography about Elon Musk, written by journalist Walter Isaacson, will hit the shelves. Within its pages, an astonishing revelation comes to light: the Tesla CEO and singer Grimes discreetly welcomed their third child into the world.

Following several divorces, Elon Musk found love in 2018 with singer Grimes, also known as Claire Boucher. In 2020, the couple celebrated the birth of their first child, initially named X Æ A-12 but later renamed X Æ A-XII due to California’s regulations against using numbers in names. Grimes attempted to explain the origins of this unconventional name on Instagram, describing it as follows: “X, the unknown variable, Æ, which I pronounce ‘Ai’ for love or artificial intelligence, A-12, which is the precursor to the SR-17 (our favorite aircraft), no weapons, no defenses, just speed. Great in battle, but non-violent. The A also stands for ‘Archangel,’ my favorite song.” Despite ongoing rumors of separation, Elon Musk and Grimes welcomed their second child in 2021, a daughter born to a surrogate mother, initially named Exa Dark Sideræl but later renamed ‘Y’.
