Elon Musk’s estranged oldest daughter, Vivian Wilson, has admitted that she doesn’t “actually know” how many children have been born to her father.

“I will say I do not actually know how many siblings I have, if you include half-siblings,” the 20-year-old told Teen Vogue when asked about the family dynamic. “I found out about the Shivon Zilis thing at the same time everyone else did. I had no idea before that.”

Zillis, an executive at Musk’s neurotechnology company Neuralink, announced late last month that she had welcomed her fourth child with the controversial billionaire, though it’s unknown when the baby boy was actually born.

Musk is publicly known to have as many as 14 children with four different women. Of those kids, Wilson says she only knows with the ones Musk shares with her mother and his ex-wife, Canadian author Justine Wilson.

The former couple welcomed their first child, Nevada, in 2002, though he tragically died at just 10 weeks old. The pair had five more children during their marriage, including Vivian and her twin brother Griffin, and triplets Damian, Saxon and Kai.

Wilson says she and her mother don’t keep up with any of the children Musk has since welcomed with other women. Along with his four children with Zillis, he shares three kids with singer Grimes. Conservative author Ashley St. Clair also claims to have secretly welcomed a child with Musk.

“I found out about Grimes having a second child because a drag queen posted about it on Reddit,” Wilson told Teen Vogue. “I wasn’t in communication with anyone in that family, which still holds true.”

Wilson has spoken openly about her strained relationship with Musk. After coming out as transgender in 2022, Wilson says things only got worse due to her father’s uber-conservative views. Musk has continued to misgender and deadname Wilson, saying she was “killed by the woke mind virus.”
