Conservative influencer Ashley St. Clair has revealed for the first time how her son with Elon Musk was conceived — as she alleged her multibillionaire 𝑏𝑎𝑏𝑦 daddy initially offered her well over $15 million to keep quiet about their kid.

The 26-year-old claimed their son Romulus, who is now 7 months old, was conceived when they had 𝓈ℯ𝓍 during a New Year’s trip to St. Barts — rather than him just offering up his sperm, the Wall Street Journal reported Tuesday.

The Tesla billionaire, 53, is known to have fathered at least 14 𝘤𝘩𝘪𝘭𝘥ren with four women, including several who were conceived via sperm donations.

However, the WSJ suggested he could have many, many more 𝘤𝘩𝘪𝘭𝘥ren out in the world, citing sources.

Musk has propositioned women on his X social media platform and offered his sperm — including crypto influencer Tiffany Fong, who declined, sources told the newspaper.

St. Clair, who previously said she embarked on a brief relationship with the world’s richest man after he made contact via X in May 2023, claimed Musk started joking that they should “pick a name” for their future 𝘤𝘩𝘪𝘭𝘥 the very first time they had 𝓈ℯ𝓍.

She alleged that he frequently spoke to her about having his 𝘤𝘩𝘪𝘭𝘥ren over the course of their tryst.

Then during their New Year’s Eve jaunt, St. Clair claimed she told Musk she was ovulating and he allegedly responded: “What are we waiting for?”

The new revelations were laid bare in a wide-ranging report that accused President Trump’s Department of Government Efficiency chief of cutting deals with the women he had asked to father his 𝘤𝘩𝘪𝘭𝘥ren.

His money manager, Jared Birchall, allegedly negotiates the deals, the report stated.

After St. Clair gave 𝐛𝐢𝐫𝐭𝐡, the SpaceX founder allegedly tried to offer her an initial $15 million payment plus an additional $100,000 monthly in 𝘤𝘩𝘪𝘭𝘥 support if she agreed to strict terms.

Musk, too, made a series of bizarre demands, according to the report — including that their offspring be 𝐛𝐨𝐫𝐧 via Caesarean because he believed vaginal 𝐛𝐢𝐫𝐭𝐡 restricts the size of a 𝑏𝑎𝑏𝑦’s brain. He also said that the new𝐛𝐨𝐫𝐧 couldn’t be circumcised.

St. Clair said she went ahead with a natural 𝐛𝐢𝐫𝐭𝐡 and wanted her son circumcised given that she is Jewish.

He also demanded, as The Post reported in February, that his name be kept off the 𝐛𝐢𝐫𝐭𝐡 certificate to preserve privacy, security and confidentiality, St. Clair said.

He allegedly sent her a text at the time stressing the importance of secrecy, referring to himself as “#2 after Trump for assassination.”

St. Clair said she was hesitant to sign any deal, reportedly telling Birchall in a December phone call: “I don’t want my son to feel like he’s a secret.”

During the call, Birchall allegedly pressed St. Clair to sign an NDA, claiming word about her son would cause problems for Musk.

“(We) cannot allow people to just go and share his life information. He is the biggest lightning rod on the entire planet,” Birthall allegedly said, according to the report.

Musk, for his part, has never publicly confirmed he fathered a 𝘤𝘩𝘪𝘭𝘥 with St. Clair. He has also questioned the paternity, writing in an X post: “I don’t know if the 𝘤𝘩𝘪𝘭𝘥 is mine or not, but am not against finding out,” Musk wrote on X. “No court order is needed.”

The Wall Street Journal report stated that a New York court ordered a paternity test eventually came back with a 99.9999% probability that Musk is the dad.

The details emerged months after St. Clair first went public in February with the claim she’d had a 𝑏𝑎𝑏𝑦 with Musk.

“Five months ago, I welcomed a new 𝑏𝑎𝑏𝑦 into the world. Elon Musk is the father,” she wrote 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.”

“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.”

After posting the tweets, St. Clair said Musk allegedly pulled the initial $15 million offer.

Then, after she took him to court for the paternity and custody battle, she claimed her support was dropped to $40,000 a month.

She alleges the monthly support payments dropped to $20,000 when the WSJ published its report.
