Elon Musk has revealed unexpected news regarding his 13th child.
Previously, it was reported that the SpaceX CEO had a new addition to his family, a child with Ashley St. Clair.
The child is believed to have been born in September 2024, but St. Clair kept the paternity undisclosed until several months had passed, eventually revealing that her son was fathered by the billionaire.
In response to the revelation, Musk expressed uncertainty about being the father.
“I don’t know if the child is mine or not, but am not against finding out,” Musk stated last March amid allegations from St. Clair. He added: “No court order is needed. Despite not knowing for sure, I have given Ashley $2.5M and am sending her $500k/year.”
St. Clair claimed that she had asked Musk to take a paternity test to confirm his paternity, but alleged that he declined to do so.
In April, the Wall Street Journal obtained receipts between St. Clair and Musk, which included a paternity test result showing there was a ‘99.9999%’ likelihood that Musk is indeed the father.
Recently, the technology entrepreneur publicly acknowledged that the child is his and announced his intention to seek full custody of the one-year-old.
I will be filing for full custody today, given her statements implying she might transition a one-year-old boy

“I will be filing for full custody today, given her statements implying she might transition a one-year-old boy,” Musk tweeted today (January 12).
This statement follows St. Clair’s expression of regret over previous transphobic comments she had made.
I feel immense guilt for my role. And even more guilt that things I have said in the past may have caused my son’s sister more pain. Idrk how to make amends for many of these things but I have been trying incredibly hard privately to learn + advocate for those within the trans…

A person on Twitter questioned her: “You’ve previously engaged in blatant transphobia, how do you feel about trans people in the wake of noticing how the far right truly is?”
In response, St. Clair admitted: “I feel immense guilt for my role. And even more guilt that things I have said in the past may have caused my son’s sister more pain. Idrk how to make amends for many of these things, but I have been trying incredibly hard privately to learn + advocate for those within the trans community that I’ve hurt.”
She continued: “I also haven’t said much on this bc I have gone back and forth over whether my voice would be helpful on the issue since it will be framed as disingenuous or just turning bc I’m ‘scorned.’ Even this reply will become right wing hysteria but yeah I am sorry. Let me know how I can help.”
Despite Musk’s assertions, St. Clair has not mentioned anything about ‘transitioning’ their young son.
