The way Elon Musk sees it, he's doing his part to help the planet by becoming a father of 10.

On July 6, Business Insider reported that the Tesla CEO, 51, welcomed twins with Neuralink executive Shivon Zilis last November, citing court documents. While Elon has yet to confirm the rumor, he offered a rare glimpse inside his growing family tree.

"Doing my best to help the underpopulation crisis," he tweeted on July 7, seemingly referencing the news about his twins. "A collapsing birth rate is the biggest danger civilization faces by far."

"Mark my words," Elon continued, "they are sadly true."

He also told Page Six in an article published July 7 that he hopes to have "as many [kids] as I am able to spend time with and be a good father."

While the CEO of Space X is keeping the details surrounding his twins under wraps—such as their names, sex and birthdate—Business Insider published court documents that said the babies were born in Austin, Texas, where Elon currently resides.

An Austin judge granted their request the following month, per the court documents.

The court documents, which E! News has not verified, reportedly stated that Elon and Shivon asked a Texas county court to change their twins' names in April so they could "have their father's last name and contain their mother's last name as part of their middle name."

Shivon, who has yet to publicly comment on the arrival of the twins, has just as impressive of a background as Elon. She earned a ranking on Forbes' 30 under 30 and LinkedIn's 35 Under 35. In addition, the Neuralink executive, who graduated from Yale, is also on the board of the Vector Institute for Artificial Intelligence and Alberta Machine Intelligence Institute.

E! News has reached out to Shivon and to Elon's lawyer for comment, but hasn't heard back.

Elon and Shivon reportedly had their twins a month before Grimes welcomed her second child, a baby girl via surrogate, with the businessman. In the singer's March interview with Vanity Fair, the duo's little one made her presence known and was heard crying from another room.

Elon and Grimes, who broke up in March, named their daughter Exa Dark Sideræl Musk, calling her Y—a cute nickname considering their 2-year-old son, X Æ A-12 Musk, is known as "Baby X."


Elon appeared to get sentimental about his children growing up so fast, telling Page Six, "My eldest are off to college, and teenagers don't want to spend much time with their parents. I wish they would (sigh)."

Maye Musk, Mother

Maye was born in Saskatchewan, Canada and emigrated with her parents to Pretoria, South Africa in 1950, when she was 7. She and Elon's father, Errol, split in 1979.

After Elon moved to Canada at age 17, Maye obtained Canadian citizenship by birthright and moved there too, as did his siblings.  There, she established a dietician practice and became President of the Consulting Dieticians of Canada, per Forbes. She also worked as a model.

In 2019, after Elon sold his company Zip2 to Compaq for more than $300 million, he bought his mom an apartment in New York City, where she lived for 13 years and continued her modeling career. She is signed to the IMG Models agency. 

"I brought my children up like my parents brought us up when we were young: to be independent, kind, honest, considerate and polite," Maye wrote in her essay. "I taught them the importance of working hard and doing good things."

Errol Musk, Father

Elon's father is an engineer and like Elon, was born in South Africa. In the 2015 biography Elon Musk: Tesla, SpaceX and the Quest for a Fantastic Future, author Ashlee Vance wrote that Elon and his dad had a difficult relationship. In an emotional 2017 Rolling Stone interview, Elon criticized his father and talked about his upbringing, saying that after his parents split, he moved in with his dad, which, he said, "was not a good idea."

Errol told Rolling Stone, "I love my children and would readily do whatever for them."

In a 2015 Forbes interview, Elon's dad said he used to take his kids on trips overseas. "Their mother and I split up when they were quite young and the kids stayed with me," he said. "I took them all over the world."

After divorcing Elon's mother Maye, Errol married Heide, mother of Jana Bezuidenhout, who was 4 years old at the time. Errol and Heidi went on to have two daughters together before they too broke up. In 2017, Errol and Jana had a baby together, son Elliot.  

Errol told the U.K.'s Sunday Times in 2018 that Jana contacted him the previous year. "We were lonely, lost people," he told the newspaper. "One thing led to another — you can call it God's plan or nature's plan."

He added in his Sunday Times interview that he did not consider Jana his stepdaughter and that she was raised away from the family for long periods of time. He said he helps support her and their son and sees them regularly, although he does not live with them.

Kimbal Musk and Tosca Musk, Brother and Sister

Kimbal, born in 1972, is a restauranteur. He is the founder of The Kitchen, a collective of 5 restaurants that source directly from local farmers, Forbes reported in 2018. He also runs a non-profit, Big-Green, that has built 200 learning gardens in schools across the U.S., the outlet said.

Tosca, born in 1974, is a filmmaker. In 2017, she founded Passionflix, a female-focused streaming service that targets the billion-dollar romance novel industry, according to Forbes.


Justine Wilson, First Ex-Wife (2000-2008)

Elon and Canadian-born Justine, his college sweetheart from Queen's University in Ontario, married in 2000.  In a 2010 article she penned for Marie Claire, titled I Was a Starter Wife: Inside America's Messiest Divorce, Justine said that while dancing at their wedding reception, Elon told her, "I am the alpha in this marriage."

"I shrugged it off," Wilson wrote, "just as I would later shrug off signing the postnuptial agreement, but as time went on, I learned that he was serious."

The two welcomed their first child, son Nevada Alexander, in 2002. The baby died at age 10 weeks from Sudden Infant Death Syndrome (SIDS). "Nevada went down for a nap, placed on his back as always, and stopped breathing," Justine wrote in her article.

The couple pursued IVF to conceive again went on to welcome five more boys—twins and triplets.

In 2008, Elon filed for divorce. They share custody of their sons and daughter.

Elon and Justine welcomed their triplets in 2006. 

Tallulah Riley, Ex-Wife (2010-2012, 2013-2016)

Elon and Tallulah, who played host greeter Angela on HBO's Westworld, married in 2010.  "It all happened very fast," she told CBS News. "We were engaged after, I think, two weeks of knowing each other." 

The two divorced in 2012, remarried a year later before the pair divorced again in 2016.

Amber Heard, Ex-Girlfriend (2017)

Elon and Amber went public with their romance in early 2017, a year after she filed for divorce from Johnny Depp and Elon and second wife Tallulah Riley divorced for the second time. Months later, Elon and Amber called it quits

"I just broke up with my girlfriend," Elon told Rolling Stone. "I was really in love, and it hurt bad...Well, she broke up with me more than I broke up with her, I think."


Grimes: Ex-Girlfriend (2018-2022)

Elon and the singer dated on and off for about four years, starting in 2018. The two share two children. In September 2021, Elon told Page Six that he and Grimes "are, I'd say, probably semi-separated," adding, "It's mostly that my work at SpaceX and Tesla requires me to be primarily in Texas or traveling overseas and her work is primarily in LA. She's staying with me now and Baby X is in the adjacent room."

In a March 2022 interview with Vanity Fair, the singer said she and Elon "live in separate houses" and are "best friends."

She later tweeted, "Me and E have broken up *again* since the writing of this article haha, but he's my best friend and the love of my life, and my life and art are forever dedicated to The Mission now." 


X Æ A-Xii Musk, Son

In 2020, Elon and then-girlfriend Grimes welcomed their first child together, a son. They soon modified the spelling of his name in order to meet California's legal guidelines, which only permit letters from the English alphabet. Switching over to roman numerals, the parents agreed to spell his name, X Æ A-Xii.

"X, the unknown variable," Grimes explained on Twitter. "Æ, my elven spelling of Ai (love &/or Artificial intelligence) A-12 = precursor to SR-17 (our favorite aircraft). No weapons, no defenses, just speed. Great in battle, but non-violent." 

Grimes continued, "A=Archangel, my favorite song" with an accompanying a rat and sword emoji. "Metal rat."

Exa Dark Sideræl Musk, Daughter

In her Vanity Fair interview, Grimes she and Elon privately welcomed a baby girl, their first daughter, via surrogacy.

"Exa is a reference to the supercomputing term exaFLOPS (the ability to perform 1 quintillion floating-point operations per second)," she said. "Dark, meanwhile, is ‘the unknown. People fear it but truly it's the absence of photons. Dark matter is the beautiful mystery of our universe.'"

Sideræl—pronounced "sigh-deer-ee-el," is "the true time of the universe, star time, deep space time, not our relative earth time," and a nod to her favorite Lord of the Rings character, Galadriel, who "chooses to abdicate the ring."

Twins With Shivon Zilis

Business Insider published court documents on July 6 that stated Elon welcomed twins with Neuralink executive Shivon Zilis in November. The babies were reportedly born in Austin, Texas, where the businessman lives. He also seemingly weighed in on the report on Twitter, writing, "Doing my best to help the underpopulation crisis.
