The name of the child thatĀ Ashley St. ClairĀ said sheĀ welcomedĀ withĀ Elon MuskĀ earlier this year has been revealed.
According to a new report from the Wall Street Journal, the 26-year-old influencer’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 theĀ Daily MailĀ 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.”
MuskĀ denied that heĀ “financially retaliated”Ā against St. Clair and their child. On Monday, March 31, the Tesla founder responded to a tweet fromĀ Laura Loomer, who was reacting to a video of the 26-year-old influencerĀ 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 donāt know if the child is mine or not, but am not against finding out. No court order is needed,” heĀ wrote on X. “Despite not knowing for sure, I have given Ashley $2.5M and am sending her $500k/year.”
