Elon Musk's Ex Calls Him 'Gatling Gun of Sperm' in New Documentary About His Private Life

Ashley St. Clair, Elon Musk's former partner and the mother of one of his children, alleges in Alex Gibney's new documentary Musk that the Tesla chief encouraged her to have children and later operated like a 'Gatling gun of sperm in his DMs'.

The film was screened at the Toronto International Film Festival ahead of its 9 October cinema release, and St. Clair said their relationship began before she gave birth to their son, Romulus, in 2024.

In the documentary, the 28-year-old says she was uneasy about becoming a 'baby mama' to Musk and claims he said he wanted a 'legion of children' before what he predicted would be a future 'civil war'.

Elon Musk Claims Feature in Documentary Chapter on Fatherhood

St. Clair's allegations appear in a section of Musk titled 'Legion', which examines Musk's relationships and children.

She claims Musk contacted numerous women and described his behaviour with the phrase 'Gatling gun of sperm in his DMs', suggesting some of those interactions eventually resulted in children.

The former conservative social media personality also discusses her concerns about becoming publicly associated with Musk through motherhood.

Her account is presented alongside material about Musk's children with other women, including musician Grimes, and testimony from his former wife Justine Musk.

The documentary broadens its examination through interviews with people who have known Musk personally. His father, Errol Musk, also appears, while Gibney uses the different accounts to explore Musk's family relationships alongside his public career.

St. Clair says tensions continued after Romulus was born. She alleges that she declined to sign a non-disclosure agreement that she believed was connected to negotiations over child support following the end of their relationship.

At the Venice Film Festival premiere, St. Clair said the proposed arrangement made her consider how much she valued being able to speak publicly. She also accused Musk of having a 'complicated relationship' with the truth, a characterisation that remains her own assessment.

Elon Musk Pushes Back as Gibney Defends His Film

Musk has criticised Musk on X, describing the documentary as 'a hit piece'. Gibney, however, has said Musk had not seen the finished film.

During a post-screening discussion at TIFF, Gibney also told the audience that Musk had 'threatened to sue us' over the project.

Musk declined to participate directly in the documentary, prompting the filmmakers to use artificial intelligence to construct an on-camera representation of him.

The nearly four-hour film extends well beyond his private relationships. It traces his childhood in South Africa, his involvement with Tesla, his acquisition of Twitter, his SpaceX work and questions surrounding the environmental effects of his businesses. It also examines his involvement in the 2024 US presidential election cycle.

Elon Musk Documentary Questions His Public Narrative

Gibney also uses the film to challenge parts of the public narrative surrounding Musk's business record. During the Toronto discussion, he pointed to Tesla co-founders Marc Tarpenning and Martin Eberhard and argued that Musk was not the company's original founder or key inventor.

Eberhard appears in the documentary, while Gibney similarly credits engineers with playing major roles in SpaceX's development.

St. Clair's account, however, remains among the film's most personal elements, particularly her allegations about Musk's approach to having children and the confidentiality agreement she says she rejected.

Musk has disputed at least one part of her account. After St. Clair previously claimed she had been offered a large financial agreement not to speak publicly, Musk responded on X with a direct denial: 'She was never offered that.'
