In an unexpected and shocking announcement,  Elon Musk’s 18-year-old son Xavier has petitioned to change his gender and become a woman named Vivian Jenna Wilson. Although Xavier hasn’t spoken out too extensively about the transition, a major reason is apparently that the teen no longer lives with or wishes to be connected to their biological father “in any way shape or form.”

They’ve already legally filed to change their gender and lose their last name. This petition was filed in April — Xavier wants to take their mother’s maiden name and wrote the surprising quote about their father in the California court hearing. Xavier hasn’t commented on whether or not they get financial support from their father, who has a $213 billion dollar fortune, making him the wealthiest man alive.

50-year-old Musk had Xavier with his first wife, Canadian author Justine Wilson back in 2004. The two met at Ontario’s Queen University. They had a total of five children together and Musk still has joint custody of them. He also shares two other children with his recent ex, Canadian singer Grimes. 

No one is exactly sure why Xavier is expressing such a strong rejection when it comes to their dad, and Elon Musk hasn’t commented on it yet.  We don’t even know if he was aware of his kid’s plan before the court documents were filed.
