Elon Musk allegedly slashed ex Ashley St. Clair’s monthly child support by $80,000 after she publicly revealed she’d secretly given 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 — a deal she previously said she could not “in good conscience” sign.
The author also previously said she turned down the multimillion-dollar deal because she didn’t want her then-newborn, Romulus St. Clair, to “feel like he’s a secret.”
In the new doc, St. Clair claims Musk, now 55, cut her monthly child support payments to $40,000 after she refused to sign the NDA, then reduced them further to $20,000 after she publicly revealed their son in February 2025, per Entertainment Weekly.
The former conservative influencer says Musk was “kind” until Romulus, now 2, was born, adding, “It was almost as if he didn’t show a certain side of himself until 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 doc that her relationship with Musk began in 2023, when he started “interacting” with her on X (formerly Twitter).
“He was responding to my posts frequently. One day, he responded to one of my Mother’s Day posts [and said] that I should have more children,” St. Clair says, adding that Musk dubbed himself a “good dad” and appeared to have an “amicable” relationship with the mothers of his children.
“We should have a kid. You should have so many more kids. You should have 10 kids,” St. Clair recalls Musk telling her. “Eventually, I was like, ‘Well, what does that look like?’”
Most recently, Musk welcomed his 14th child, Seldon Lycurgus, with Neuralink executive Shivon Zilis, who recently said he ended their relationship “with no warning.”
St. Clair claims in the new doc that Musk may have more children than publicly known, saying she was contacted by other women whom Musk had been “DMing” and allegedly “offering them children.”
“There was a woman in Japan who just wanted, basically, sperm donation that he obliged,” she says. “It’s like a Gatling gun of sperm in his 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 “substantially” reduce his financial support, leaving her facing eviction.
Musk, for his part, previously claimed he had paid St. Clair $2.5 million but said he was “not against finding out” whether he was the child’s father.
More recently, at the Venice Film Festival, where “Musk” premiered, St. Clair claimed the multibillionaire had confessed in a text message before she gave birth that he wanted a “legion of children before the civil war.”
A rep for Musk didn’t immediately respond to Page Six’s request for comment.
