Austin, Texas - Elon Musk's first wife has broken her silence and shared some damning details about their relationship in a bombshell documentary.
According to People, Justine Musk – who was married to the tech mogul from 2000 to 2008 – is featured in director Alex Gibney's upcoming documentary film about her ex, where she describes how she "learned the term 'gaslighting'" through their relationship.
She claims Musk regularly made her feel "insignificant," talked down to her as if she were an employee of his, and was "constantly remarking on the ways he found me lacking."
When the couple danced on their wedding night, she claims Musk told her, "I am the alpha in this relationship."
In regard to parenting, Justine – who is the mother to six of Musk's 14 children – reveals her ex has claimed for years that he held their first child, Nevada, as he passed away from Sudden Infant Death Syndrome, but it was actually her who held the baby.
She also opens up about how Musk cut off health insurance for their daughter Vivian after learning she was transgender and has "never tried to repair things" with her, as it's "not in his nature."
Justin has previously shared what she learned from his work ethic in public speeches, but her appearance in the documentary marks the first time she has spoken about their marriage.
Back in January, after an X user posted a video of her "sharing valuable insights" about his success, Musk replied, "Justine is an amazing woman."
Elon Musk reacts to bombshell documentary: "A hit piece"
The four-hour film – which examines Musk's rise to fame, wealth, and powerful influence – premiered on Tuesday at the Venice Film Festival, and will be released in theaters on October 16.
It features a number of other interviews with people who used to be close to Musk, including Ashley St. Clair – the mother of another of his children – who revealed during a press conference at the festival that Musk offered her $40 million not to be in the film.
Since the project was announced in 2023, Musk has repeatedly described the film a "hit piece," and urged his millions of followers on X not to see it.
