Elon Musk’s estranged daughter, Vivian Jenna Wilson, has responded to the news that the Tesla CEO recently welcomed his 14th child—his fourth with Neuralink executive Shivon Zilis.
In a TikTok post, Wilson expressed a mix of sarcasm and resignation, revealing that, once again, she learned about her latest half-sibling through social media.
Wilson, who legally changed her name and distanced herself from Musk in 2022 after coming out as transgender, shared a stitched video on TikTok, referencing a past post where she expressed her frustration at discovering her father’s growing number of children online.
“This is already outdated, nevermind,” she wrote over a close-up shot of her eye. In the caption, she added, “Technically, it was through Threads this time though.”
Her reaction echoes a viral post from February, where she joked, “Wow, if I had a nickel for every time I found out I had half-siblings through Reddit, I’d have two nickels … which isn’t a lot, but it’s weird that it’s happened twice, right?” That post referred to Musk’s 13th child, whose birth had been announced by author Ashley St. Clair.
Musk first became a father in 2002 with his then-wife, Canadian author Justine Wilson, though their first child, Nevada, tragically passed away at 10 weeks old.
The couple later had five more children: twins Vivian and Griffin, and triplets Kai, Saxon, and Damian.
Since then, Musk has fathered several children across different relationships, including three with singer Grimes—X Æ A-12, Exa Dark Sideræl, and Techno Mechanicus—and now four with Zilis, the latest being Seldon Lycurgus, announced in early 2025.
In February, Ashley St. Clair also revealed that she had welcomed a baby with Musk, making it his 13th child at the time.
Wilson’s public break from Musk has been widely documented. After legally changing her name and dropping his surname, she stated in court documents that she no longer wished to be associated with her biological father “in any way, shape, or form.”
Musk has since addressed their estrangement, attributing their distance to what he referred to as the “woke mind virus” ideology.
