The former couple share two more 𝘤𝘩𝘪𝘭𝘥ren, a girl, Exa Dark Sideræl, and a boy, Techno Mechanicus. A few weeks prior to the arrival of their second 𝘤𝘩𝘪𝘭𝘥, the tech CEO also secretly fathered twins, Strider and Azure, with Shivon Zilis, an executive at one of his companies, Neuralink, in November 2021, according to court documents published by Insider.

During a May 2023 interview with The Wall Street Journal’s CEO Council, Musk spoke about his 𝘤𝘩𝘪𝘭𝘥ren’s futures. He shared that he has no plans to “automatically” give his 𝘤𝘩𝘪𝘭𝘥ren shares of his companies “if they have no interest or inclination or ability to manage” his empire.

“Nevada went down for a nap, placed on his back as always, and stopped breathing,” Wilson wrote in a 2010 essay for Marie Claire. “By the time the paramedics resuscitated him, he had been deprived of oxygen for so long that he was brain-dead.”

In her Marie Claire essay, Wilson detailed the couple’s journey to expand their family further.

While speaking to the Financial Times in October 2022, Musk said he believes Vivian doesn’t want to be associated with him because of the supposed takeover of elite schools and universities by neo-Marxists.

But Musk explained the pronunciation differently, saying on The Joe Rogan Experience podcast that “X” is spoken “like the letter” while “the ‘Æ’ is pronounced like ‘ash.’ ”

According to The Washington Post, Musk brought X Æ A-Xii to X’s offices while meeting with Trust and Safety Office Yoel Roth in October 2022. The 𝘤𝘩𝘪𝘭𝘥 was reportedly running around the building as Musk discussed the company’s future. X Æ A-Xii also made himself comfortable in the conference room, which the newspaper reported “was strewn with toys.”

Musk secretly welcomed twins, son Strider and daughter Azure, with Shivon Zilis in November 2021, according to court documents published by Insider. The twins were 𝐛𝐨𝐫𝐧 in Austin, Texas — just weeks before he and Grimes welcomed a 𝑏𝑎𝑏𝑦 girl via a surrogate.

Grimes revealed a year later in a Vanity Fair interview that she welcomed a 𝑏𝑎𝑏𝑦 girl via surrogate in December 2021, three months after the couple’s public breakup. Named Exa Dark Sideræl, the singer-songwriter explained that her name has a double meaning.

The third part of Y’s full name, Sideræl, is pronounced “sigh-deer-ee-el,” according to Vanity Fair. Grimes described the word as “a more elven” spelling of sidereal, which she defined as “the true time of the universe, star time, deep space time, not our relative earth time.”

The second meaning of Sideræl is a nod to Grimes’ favorite Lord of the Rings character, Galadriel, who “chooses to abdicate the ring.”

“Normally we [don’t] post her for her privacy, but she’s fairly unrecognizable here since shes channeling Goku,” she wrote in the comments, referring to a Dragon Ball character. The photo showed Musk’s youngest in a red onesie with super blonde spiked hair.
