(KTLA) — One of Elon Musk’s children has expressed a desire to change her name and sever ties with her billionaire father. Musk’s 18-year-old progeny, formerly known as Xavier Alexander Musk, said in a Los Angeles County Superior Court filing that she is also changing her gender identity from male to female, Reuters reports.

The April filing came one day after the teenager turned 18, reported the Los Angeles Times, which identified Musk’s child as Vivian Jenna Wilson. Now a legal adult, Wilson said she no longer wants anything to do with her businessman dad, who heads Tesla, SpaceX, and potentially Twitter.

“I no longer live with or wish to be related to my biological father in any way, shape, or form,” Wilson said in the filing. Musk, a frequent Twitter user, has not publicly addressed Wilson’s decision.

The Times reported that Musk has seven children—two with the musician Grimes and five with Wilson’s mother, writer Justine Wilson. He and Wilson also lost a 10-week-old son to sudden infant death syndrome, Yahoo reported.

On Father’s Day, Musk tweeted“I love all my kids so much.”
