The father of 14, seen above last month, threatened to sue for custody of their son after St. Clair apologized to the trans community for her previous transphobia. Getty Images St. Clair and Musk are seemingly not on good terms — in January 2026, the tech magnate threatened to sue for custody of their son, though the social media star had already sued for sole custody of Romulus in February 2025. The threat came after St. Clair apologized via social media for what she called her own past “blatant transphobia.” “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,” she tweeted in part, referring to the Tesla founder’s trans daughter Vivian Wilson. She added, “[I don’t really know] 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.” Musk responded via X at the time, “I will be filing for full custody today, given her statements implying she might transition a one-year-old boy.” St. Clair later told CNN anchor Erin Burnett, “I’m not at liberty to discuss it further, but I think anyone with more than a third-grade reading comprehension level knows what I was saying there.” Filed under
