Elon Musk Cut Ex Ashley St. Clair’s Child Support By $80,000 After She Revealed Their Son, Doc Claims

Elon Musk reportedly reduced his ex Ashley St. Clair’s monthly child support by $80,000 after publicly revealing she secretly gave birth to his 13th child.

According to claims made in the new documentary “Musk,” St. Clair, 28, was offered $15 million and $100,000 a month in child support in exchange for signing an NDA that would keep her relationship with Musk secret — an agreement she previously said she couldn’t sign “in good conscience.”

The author also previously said she turned down the multimillion-dollar deal because she didn’t want her newborn, Romulus St. Clair, “to feel like he’s a secret.”

In the new document, St. Clair claims that Musk, now 55, reduced her monthly child support payments to $40,000 after refusing to sign the NDA, then reduced them further to $20,000 after going public with their son in February 2025, according to Entertainment Weekly.

The former conservative influencer said Musk was “nice” until Romulus, now 2, was born, adding, “It was almost like he only showed a certain side of himself after I had our baby.” »

St. Clair previously revealed in a TikTok video that “things started getting weird” between her and the Tesla CEO when she became pregnant.

She explains in the new document that her relationship with Musk began in 2023, when he began “interacting” with her on X (formerly Twitter).

“He responded to my messages frequently. One day he responded to one of my Mother’s Day messages (and said) that I should have more children,” St. Clair says, adding that Musk called himself a “good father” and seemed to have an “amicable” relationship with his children’s mothers.

“We should have one kid. You should have so many more kids. You should have 10 kids,” St. Clair recalled Musk telling him. “Eventually I was like, ‘Well, what does this look like?'”

Most recently, Musk welcomed his 14th child, Seldon Lycurgus, with Neuralink head Shivon Zilis, who recently said he ended their relationship “without warning.”

St. Clair claims in the new document that Musk may have more children than is publicly known, saying she was contacted by other women who Musk had “DMed” with and who allegedly “gave them children.”

“There was a woman in Japan who just wanted a sperm donation, which he obliged,” she says. “It’s like a Gatling gun of cum in her DMs.”

St. Clair has been embroiled in a custody battle with Musk over Romulus, with her legal team alleging that the dispute led Musk to “significantly” reduce her financial support, leaving her facing deportation.

Musk, for his part, previously claimed to have paid St. Clair $2.5 million, but said he “wasn’t against finding out” whether he was the child’s father.

Most recently, at the Venice Film Festival, where “Musk” screened, St. Clair claimed the multibillionaire confessed in a text message before giving birth that he wanted “a legion of children before the Civil War.”

A representative for Musk did not immediately respond to Page Six’s request for comment.
