Elon Musk’s daughter, Vivian Jenna Wilson, has openly shared her strained relationship with her billionaire father and her siblings.

In an interview with Teen Vogue, the 20-year-old, who is transgender, admitted she isn’t sure how many siblings she has, given Musk’s multiple relationships. The billionaire has at least 12 children with three women, though author Ashley St. Clair recently claimed to be the fourth mother of his child.

Wilson revealed she discovered some of her half-siblings’ existence through Reddit, including Musk’s children with Shivon Zilis and Grimes. She joked, “If I had a nickel for every time I found out I had half-siblings through Reddit, I’d have two nickels.”

Regarding her family ties, Wilson said she doesn’t keep in touch with Musk’s side of the family, nor does her mother. “I don’t really give a f**k what they do,” she stated, adding that she’s only seen her brother X once when he was very little.
