“He was just clueless about why I’d be upset,” Grimes says in the book, saying he had even sent the photo to her father and brothers, via ET Canada.

The couple first started dating in 2018. They welcomed their son in 2020, and the next year welcomed a daughter via surrogacy. They also have a third child together, which was revealed in the book, named Techno Mechanicus, but kept that a secret.

Elon is a father to 11 children at this point.
