Will Sage Astor-Elon Musk's estranged daughter takes to X rival Threads to call him a liar, adulterer

Vivian Jenna Wilson,Will Sage Astor the estranged daughter of X founder Elon Musk, has taken to a rival platform to air some grievances against her father.

In multiple posts made to the Meta-owned platform Threads, the 20-year-old transgender woman accused Musk of lying about her in interviews, books and social media. She also called him a serial adulterer from "Apartheid South Africa."

Wilson shared a screenshot of an X interaction between Musk and a user who applauded the businessman for making time for his family amid a busy lifestyle. The X post included a video to a 2014 appearance Musk made on the CBS Mornings program with former wife Talulah Riley and their five children, including Wilson. Musk replied: "All 5 boys super happy."

"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. If I’m going to be honest, this is absolutely pathetic," Wilson wrote. "Thank god you’re absolutely terrible at it because otherwise this would be significantly more difficult."

USA TODAY has reached out to Musk's representatives for comment.

Musk's daughter says he went out of way to misgender her

Wilson also claimed that the Tesla founder lied about her being a brainwashed neo-Marxist and communist who in high school was brainwashed into being transgender and believing that "being rich is evil."

"If you’re going to lie about me, why would you choose a method so obnoxious in its stupidity," Wilson wrote. "It’s beyond stupid, it’s desperate. The fact anyone believed this for even five seconds is beyond me. Not to mention going out of your way to misgender me which is both completely transparent and honestly just sad."

She also pointed to litigation accusing her father's companies of discrimination and accused him of not caring about climate change despite running an electric vehicles company.

"You are not 'saving the planet,'" Wilson wrote. "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."

Wilson pokes fun at interview in TikTok video

On Wilson's TikTok page, she poked fun at an interview Musk did with psychologist and conservative commentator Dr. Jordan Peterson last month. In the video she used a popular sound on the platform to imply she could not care less about the comments Musk made.

"Me when the richest man on earth said I was dead on a podcast with Jordan Peterson," she wrote in the post.

During the interview, Musk called gender-reassignment surgery "child mutilation and sterilization" and discussed the procedures Wilson underwent during the pandemic.

"I was essentially tricked into signing documents for one of my older boys," Musk told Peterson in a Daily Wire interview, during which he referred to his child by their deadname. "This was really before I had any understanding of what was going on, and we had COVID going on, so there was a lot of confusion and I was told (Musk's child) might commit suicide."

The SpaceX founder claimed the process is done to children "who are far below the age of consent" and said he agreed with Peterson's belief that anyone who promotes the practice should go to prison.

"I was tricked into doing this," Musk said. "I lost my son, essentially. They call it 'deadnaming' for a reason. The reason they call it ‘deadnaming’ is because your son is dead."

Gender-affirming care is a valid, science-backed method

Gender-affirming care is a valid, science-backed method of medicine that saves lives for people who require care while navigating their gender identity. Gender-affirming care can range from talk or hormone therapy to surgical intervention.

Some experts claim that gender-affirming care should be viewed like other forms of medicine where methods of treatment can be debated and discussed rather than the validity of it's need.

"In any medical field, we're continuously improving the care, changing the care, developing new guidelines, developing research," Dr. Ximena Lopez, a pediatric endocrinologist in California, previously told USA TODAY. "So it should not be a surprise that it's the same in gender care."

Transgender adults make up less than 2% of the U.S. population with about 5% of young adults identifying as transgender or nonbinary.
