Following reports that he secretly had twins with one of Neuralink’s top executives, Elon Musk tweeted that he was doing his part to contribute to the Earth’s population.
“Doing my best to help the underpopulation crisis,” he tweeted Thursday. “A collapsing birth rate is the biggest danger civilization faces by far.” He added: “Mark my words; they are sadly true.”
According to court documents obtained by Insider, Musk welcomed twins with Neuralink’s Shivon Zilis in 2021, bringing his total number of children to nine.
The twins arrived just before Musk and Grimes welcomed their surrogate baby in December.
Currently, Musk is co-CEO of Neuralink, where the mother of the twins works as director of operations and special projects.
Earlier this month, his 18-year-old child Vivian Jenna Wilson was granted a name change and gender change in California, removing “Musk” from her legal name and selecting a first name reflective of her gender identity.
Grimes revealed in March that she and Musk had welcomed a second child, Exa Dark Siderael. The pair nicknamed her “Y,” after her older brother “X.”
During an interview with Vanity Fair, Grimes was asked if she was still with Musk, and she responded, “There’s no real word for it … I would probably refer to him as my boyfriend, but we’re very fluid. We live in separate houses. We’re best friends. We see each other all the time … We just have our own thing going on, and I don’t expect other people to understand it.”
She added, “We’ve always wanted at least three or four.”
Later, Grimes posted a series of tweets that revealed that she and Musk had broken up.
