The “Oblivion” singer shared rare insight into her co-parenting dynamic with the tech mogul, noting that their son X Æ A-12, 3, and daughter Exa Dark Sideræl Musk, 19 months, are following in Elon’s footsteps when it comes to interest in life beyond the stars.
“X knows a lot about rockets,” Grimes told Wired in an interview published Aug. 8. “It’s crazy. He knows more about rockets than me.”
In fact, the pair’s little boy already as a knack for astronomical engineering. “We had to stop giving him toys, because if they’re not anatomically correct, he gets upset,” the 35-year-old added. “He’s a little engineer, for sure. But his obsession with space is bordering on, ‘Is this healthy?'”
What’s more, she revealed that the 3-year-old was impacted the April explosion of Starship, a rocket launched by Elon’s spacecraft company SpaceX.
“When X saw Starship blow up, he had, like, a three-day PTSD meltdown,” Grimes recalled. “Every hour, he was waking up and going, ‘Starship …’ and I had to rub his back.”
