According to a new report from The Wall Street Journal (WSJ), the infant -- previously identified by the initials R.S.C. is named Romulus.

A spokesperson for Ashley Clair confirmed both the paternity results and the child's name to PEOPLE magazine. Twenty-six-year-old Ashley Clair publicly announced in February 2025 that she and Elon Musk had welcomed a son together in September 2024. At the time, she explained her prior decision to keep the news private, but had to later go public to protect her child. The two are said to have met in early 2023 via social media and Elon Musk reportedly invited her to visit Twitter office in San Francisco,
When Ashley Clair announced she is mother of Elon Musk's baby
"Five months ago, I welcomed a new baby into the world. Elon Musk is the father," she wrote in a post on X. "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."
Ashley Clair added, "I intend to allow our child to grow in a normal and safe environment. For that reason, I ask that the media honor our child's privacy, and refrain from invasive reporting."
On March 29, Ashley Clair was featured in a Daily Mail video, where she was shown handing over the keys to her Tesla Model S. She claimed she was selling the vehicle due to a significant reduction—reportedly 60%—in the child support payments she was receiving from Musk. A WSJ report recently stated that Musk offered Ashley Clair $15 million and $100,000 a month in support in exchange for her silence about the child.

Elon Musk said he is 'unsure' of her claim
Musk, however, refuted her claims in a response posted to Twitter on March 31. Replying to a tweet by political commentator Laura Loomer, who shared the video, the Tesla CEO denied any financial retaliation against Ashley Clair or their child. "I don’t know if the child is mine or not, but am not against finding out. No court order is needed," he wrote. "Despite not knowing for sure, I have given Ashley $2.5 million and am sending her $500,000 a year."
With this confirmation, Romulus becomes Musk’s 14th child. He shares his other children with three different women.
