Elon Musk and singer Grimes welcome second child

Grimes and Elon Musk’s Christmas present was a new baby.

The once-and-apparently-future couple secretly welcomed a second child in December, the 33-year-old accidentally revealed to Vanity Fair in a new cover story published Thursday (March 10).

The baby girl, born via surrogate, is named Exa Dark Sideræl, but the new parents call her Y, Grimes said. Son X Æ A-Xii, born in May 2020, goes by X.

It’s unclear if they ever intended to reveal their new family member, as Vanity Fair only got the scoop when reporter Devin Gordon literally heard her crying upstairs during the interview.

As for mum and dad, that seems to be a bit more complicated.

“There’s no real word for it,” Grimes told Vanity Fair. “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.”

They’re happy though, at least.

“This is the best it’s ever been,” she said. “We just need to be free.”

Grimes and Musk went public with their relationship at the Met Gala in 2018, months after the 50-year-old SpaceX founder split from actress Amber Heard. They announced their breakup in September. – New York Daily News/Tribune News Service
