According to a new report, the 26-year-old influencer’s son with the Tesla founder is named Romulus

Elon Musk offered to pay Ashley St. Clair a hefty sum to keep their child a secret. According to a report from The Wall Street Journal, the Tesla founder, 53, offered to pay the 26-year-old influencer a one-time payment of $15 million, as well as $100,000 a month in support, to keep quiet about their infant son. A source close to St. Clair confirmed with PEOPLE that Musk offered St. Clair the money in exchange for her silence about the child. The insider can also confirm that similar agreements had been negotiated with other mothers of Musk’s children. A representative for Musk did not immediately respond to PEOPLE’s request for comment.

Elsewhere in the report from the Wall Street Journal, it was revealed that St. Clair’s infant son, who was previously referred to as R.S.C., is named Romulus. The article also revealed the results of Musk’s paternity test in the case. According to a report from Labcorp, Musk’s “Probability of Paternity” was 99.9999%. A spokesperson for St. Clair confirmed to PEOPLE that a paternity test showed there is an almost 100% probability of paternity, as well as the infant’s name. In February 2025, St. Clair posted an announcement to X, revealing that she and Musk welcomed a child together in September 2024. Musk is also the father of 13 other children, whom he shares with three other women.

“Five months ago, I welcomed a new baby into the world. Elon Musk is the father. I have not previously disclosed this to protect our child’s privacy and safety, but in recent days it has become clear that tabloid media intends to do so, regardless of the harm it will cause,” she wrote at the time. “I intend to allow our child to grow in a normal and safe environment,” St. Clair continued. “For that reason, I ask that the media honor our child’s privacy, and refrain from invasive reporting.

” On Saturday, March 29, St. Clair spoke to the Daily Mail on camera as she handed over the car keys to her Tesla Model S. She told the outlet she was selling the car to compensate for the “60 percent cut that Elon made to our son’s child support.” Musk denied that he “financially retaliated” against St. Clair and their child. On Monday, March 31, the Tesla founder responded to a tweet from Laura Loomer, who was reacting to a video of the 26-year-old influencer selling her Tesla to supplement money for child care. In his response,

Musk denied St. Clair’s claims that he “financially retaliated” against the son that they share, saying “despite not knowing for sure” if the child is his, he’s given her child support. “I don’t know if the child is mine or not, but am not against finding out. No court order is needed,” he wrote on X. “Despite not knowing for sure, I have given Ashley $2.5M and am sending her $500k/year.”
