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 s*x 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 s*x.

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.
