Who is Musk's trans daughter Vivian who 'no longer wants to be related to him'?

Billionaire Elon Musk's trans daughter, born Xavier Alexander, has requested that her name be officially changed to Vivian Jenna Wilson, saying she 'doesn't want to be related to him'. The 18-year-old and her twin brother Griffin were born in 2004 to Musk's ex-wife Justine Wilson with help from IVF. Her mother, a Canadian author, parted ways with Musk in 2008.
