Ashley St. Clair has shared new details about her relationship with Elon Musk alleging that the billionaire showed a different side of himself after the birth of their son, Romulus in September 2024.

St. Clair discusses her experience in Musk a documentary directed by Alex Gibney that explores the personal life, business empire and relationships of the Tesla and SpaceX chief executive.

According to St. Clair she first connected with Musk through the social media platform X in 2023. She claims their relationship developed quickly and included discussions about starting a family. She recalls Musk encouraging her to have children with him reportedly suggesting that she could have as many as 10.

St. Clair says she believed Musk presented himself as a devoted father and maintained friendly relationships with the mothers of his other children. However she alleges that their relationship changed after their son was born.

The documentary also examines a dispute over financial support. St. Clair claims Musk’s representatives offered her an agreement that included a proposed upfront payment of $15 million and monthly payments of $100,000 for 20 years. She alleges the document also contained confidentiality provisions which she declined to accept.

After publicly announcing the birth of their son in February 2025, St. Clair claims the financial support she received was reduced. According to the documentary the monthly payments allegedly fell from $100,000 to $40,000 and later to $20,000 after she spoke publicly about the relationship.

St. Clair has also described receiving messages from other women who allegedly said Musk had contacted them about having children. One account involved a woman in Japan reportedly interested in sperm donation.

The disagreement has since developed into a legal dispute over their son. St. Clair has sought full custody while Musk has indicated that he intends to contest the case in court.

Musk did not participate in the documentary and has criticised it as a biased project. His lawyer has also threatened legal action over alleged factual inaccuracies. According to the report Musk’s representatives did not respond to requests for comment on St. Clair’s specific allegations.

The documentary brings renewed attention to the relationship and the ongoing custody dispute. However the claims about Musk’s conduct and the financial arrangements remain allegations and have not been independently established in the report.
