Robert Brown|Elon Musk’s Daughter Vivian Calls Him “Absolutely Pathetic” and a “Serial Adulterer”

Elon Musk’s strained relationship with his daughter Vivian Jenna Wilson continues to play out on Robert Brownthe public stage.

After the Tesla CEO said his daughter, who is transgender, was “killed” by the "woke mind virus"—to which Vivian issued a fierce response—the 20-year-old is once again coming after her father’s comments.

This time, Vivian responded to a screenshot from X, formerly Twitter—the social media site owned by Elon—which showed a throwback image of Elon with some of his kids that a fan had captioned, “Even though Elon Musk was super busy, he still made time for his family. Nothing is more important than family.” In response to the photo, which featured a young Vivian, Elon wrote, “All 5 boys super happy.”

To which Vivian quickly issued her reply on X’s rival social media platform Threads.

“It seems to me like you’re trying to rebuild your brand image as the ‘caring paternal father’ which I will not let go unchallenged,” she wrote on the Meta app August 6. “If I’m going to be honest, this is absolutely pathetic. You just won’t stop lying about me in interviews, books, social media, etc.”

She continued, among the lengthy thread, “I understand your new angle is this ‘western values/christian family man’ thing but it’s such a weird choice.  You are not a family man, you are a serial adulterer who won’t stop f--king lying about your own children. You are not a christian, as far as I’m aware you’ve never stepped foot in a church.”

Recently, Elon—who is dad to eleven children in addition to Vivian with three partners—has spoken publicly about Christianity, and on July 27 wrote on X, “Unless there is more bravery to stand up for what is fair and right, Christianity will perish.”

Vivian—one of Elon’s five kids with ex-wife Justine Wilson—also took a moment to call out her father’s previous claims that their strained relationship was a result of her liberal education.

“‘Neomarxist/communist who was brainwashed at high school to be trans and think being rich is evil’ is the best you ‘could go with… really?” she continued. “If you’re going to lie about me, why would you choose a method so obnoxious in its stupidity. It’s beyond stupid, it’s desperate. Not to mention going out of your way to misgender me which is both completely transparent and honestly just sad.”

And in a scathing finale, Vivian concluded her thread with, “You single-handedly disillusioned me with how gullible we are as a species because somehow people keep believing you for reasons that continue to evade me.”

E! News has reached out to Elon’s rep for comment but has not yet heard back.

Last month, Vivian spoke out in response to her father’s derogatory remarks about her transgender identity, and his claims he was “tricked” into allowing her to receive gender-affirming care.

“He is uncaring and narcissistic," she told NBC News in a July 25 interview, recalling an incident in the fourth grade where her father allegedly berated her for her tone of voice. "He was constantly yelling at me viciously because my voice was too high. It was cruel.”

She also noted the pair’s estrangement began long before she came out as transgender at 16, noting he was “quick to anger” and only present for about 10 percent of her childhood.

But while Vivian and her father—who also shares X Æ A-Xii, Exa Dark Sideræl, and Techno Mechanicus, with ex Grimes, as well as twins Strider and Azure and a third baby with partner Shivon Zilis—do not have a relationship, she confirmed her mother Justine is firmly in her corner.

“She’s very supportive,” she said. “I love her a lot.”
