Elon Musk has made an unexpected announcement about his 13th child.
Last year, it was reported that the SpaceX founder had welcomed another child, this time with Ashley St. Clair.
The baby’s believed to have been born in September 2024, but St. Clair didn’t publicly reveal that her son was the multibillionaire’s child until months later.

When it went public, Musk claimed that he didn’t know if the baby was actually his.

“I don’t know if the child is mine or not, but am not against finding out,” he said last March in light of her accusations that he was the father, adding: “No court order is needed. Despite not knowing for sure, I have given Ashley $2.5M and am sending her $500k/year.”
She responded at the time, saying that she’d requested he take a paternity test to confirm if her son was his or not, but he allegedly refused.

Fast forward to April, and the Wall Street Journal got its hands on receipts between St. Clair and Musk, which included a paternity test result showing there was a ‘99.9999%’ chance that Musk is the father.

Now the tech mogul appears to have publicly confirmed that the child is, in fact, his, as he pledged to get 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,” Musk tweeted today (January 12).
His comment comes after St. Clair, who was once a well-known right-wing activist, expressed her regrets about previous transphobic remarks she’d made.
Someone tweeted 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?”
