Elon Musk and Grimes now have a daughter, nicknamed Y

The multi-entrepreneur Elon Musk and the musician Grimes have a new child, whose birth had been kept secret until now. Her name: Exa Dark Sideræl Musk. It is a girl, and her parents call her more commonly Y.
The 33-year-old mother revealed the existence of their second child together, a little one born in December, in a river interview with Vanity Fair published Thursday
The parents required the services of a surrogate because of fears of complications, said Grimes, who described her first pregnancy as complicated.
The arrival of the couple's first child, a boy born in May 2020, had been much publicized. Notably his first name, X Æ A-12, or more simply, X.
Elon Musk, boss of the companies Tesla, SpaceX and the richest man in the world, had declared in the fall to be semi-separated from the singer.
I'd probably call him my boyfriend, but we're very fluid, Grimes, Claire Boucher by her real name, explained in the interview. We live in separate houses. We're best friends. We see each other all the time I don't expect people to understand.
She noted that she and Elon Musk plan to have more children together.
The name Exa Dark Sideræl was chosen for its spatial and technological references. Exa, for an ultra-powerful computing machine. Sideræl, for sidereal. And Dark, for the unknown of the absence of photon and dark matter, the wonderful mystery of our universe, explained the artist.
She does not exclude that her daughter wants to change her name in the future. And wishes that she is largely preserved from the public and the media.
The best situation here is me educating the little one, and him educating the little one, Grimes said from her home in Austin, Texas, while Elon Musk's main residence is just south of the state, where SpaceX's space base is located.
In November, the blond boy X had appeared on his father's lap during a virtual presentation on the company's new rocket.
Divorced three times, Mr. Musk, 50, is now an eight-time father, with one child dying at 10 weeks
