The Tesla founder has 14 children with four different women

Elon Musk.

Elon Musk allegedly said that he fathered a child with a Japanese pop star and would give his sperm to anyone to have a baby, according to a New York Times report.

The new report details how the 53-year-old businessman’s private life changed after he joined the campaign trail for President Donald Trump, including alleged drug usage and family drama. The father of 14, who’s never been shy when it comes to his feelings about having more kids, allegedly told Ashley St. Clair that he was the father of a child with an unnamed Japanese pop star and that he would give his sperm to anyone to have a baby.

“He made it seem like it was just his altruism and he generally believed these people should just have children,” St. Clair told the outlet.

Representatives for Musk did not respond to PEOPLE for comment. PEOPLE reached out to representatives for St. Clair and they had no comment.

Musk first became a father in 2002 when his ex-wife, Canadian author Justine Wilson, welcomed their son Nevada Alexander, who tragically died at 10 weeks old. The two went on to have five more children: twins Vivian and Griffin and triplets Kai, Saxon and Damian.

In 2020, two years after Musk and singer Grimes were first linked, the two announced they welcomed their first child, X Æ A-12, together. The former couple share two more children, a girl, Exa Dark Sideræl, and a boy, Techno Mechanicus.

A few weeks prior to the arrival of their second child, the tech CEO also secretly fathered twins, Strider and Azure, with Shivon Zilis, an executive at one of his companies, Neuralink, in November 2021, according to court documents published by Insider. The pair then welcomed daughter Arcadia in February 2024.

In February 2025, St. Clair revealed that she and Musk had welcomed a child, whose name was later revealed to be Romulus. Zilis then announced that she and Musk had secretly welcomed baby No. 4, son Seldon Lycurgus, though it’s unclear when.

The former Senior Advisor to the President of the United States has reportedly spoken privately about wanting to produce a “legion-level” of children before the end of the world.

According to an April report from the Wall Street Journal, Musk views his kids as a “legion,” a word that refers to a military unit used by the Roman army that consisted of thousands of soldiers.

“To reach legion-level before the apocalypse, we will need to use surrogates,” Musk allegedly texted St. Clair while she was pregnant with their child, who was born earlier this year. (In another nod to Rome, the newspaper reported that their son is named Romulus, who, according to legend, founded the city with his twin brother Remus, then murdered him after an argument.)

The newspaper also alleged in their report that Musk has used X, the social media platform formerly known as Twitter that he bought in 2022, to try and find more women to have his babies.

In response to the report, published on Tuesday, April 15, Musk tweeted, “TMZ >> WSJ.”
