Grimes was friends with Shivon Zilis before she had twins with Elon Musk, according to a new book.
Isaacson wrote that the Neuralink director decided to have children after Musk spoke to her about his population doomsday fears.
Later, when Grimes learned of Musk's children with Zilis, Isaacson said she was "outraged."
Grimes wrote the post in response to a photo Isaacson posted on X of Zilis and Musk with their two children.
"So glad we had such a wonderful talk, was insanely overdue," Zilis wrote.
