Grimes shares news of secret second child with Elon Musk
Grimes and Elon Musk had a daughter named Exa Dark Sideræl Musk, and nicknamed Y, in secret this past December, the artist told Devin Gordon in an interview for Vanity Fair's April 2022 cover story. She revealed the news accidentally, it seems, when Gordon heard a baby crying in Grimes' Austin home — though she'd told him that she and Musk's 22-month-old son, X Æ A-Xii Musk (nicknamed X), was with his father — and asked her if she'd had a second child. “I’m not at liberty to speak on these things,” Grimes told him.
