On Wednesday, a Los Angeles County Superior Court judge granted the teen’s request to legally change her name to Vivian Jenna Wilson, court records show. (Her new last name is the maiden name of her mother, Justine Wilson.)

The judge also recognized Vivian’s gender as female and ruled for the issuance of a new birth certificate to reflect the changes, per the docs.

PEOPLE has contacted Vivian for comment.

Vivian is one of five children whomJustine Musk, a 49-year-old Canadian author, shares with the 50-year-old businessman, the richest man in the world. Their first child tragically died when he was 10 weeks old from sudden infant death syndrome in 2002.

The pair, who tied the knot in 2000, separated in 2008.

TMZwas first to report on the ruling.

Although neither the Tesla CEO nor the author has spoken publicly about the ruling, earlier this week, Justine shared a snippet of afamily chatshe had with one of her 18-year-olds.

“‘I had a weird childhood,’ my 18 year old said to me. ‘I can’t believe I’m as normal-seeming as I am,'” Justine wrote on Twitter Monday, the same day that news of the court documents began circulating.

The mom, who did not specify if the conversation was with Vivian or her twin, added that she told her child, “I’m very proud of you.”

“I’m proud of myself,” the teen added.

Musk, who also shares two children with musicianGrimes, shared a brief message about his children over the weekend.

“Happy Father’s Day,” the billionaire wrote, adding in a separate message, “I love all my kids so much.”

In the past, Musk has been vocal on Twitter regarding his opinions about preferred pronouns for transgender and nonbinary people.

After being criticized in December 2020 for a since-deleted tweet seemingly mocking the use of preferred pronouns,the SpaceX CEO saidthat while he “absolutely” supported transgender people, he believed “all these pronouns are an esthetic nightmare.”

Nearly five months prior, in July 2020,Musk tweeted, “Pronouns suck.”

In May 2022, one month after his daughter’s court filing, Musk said that he plans tovote for Republican candidatesmoving forward, specificallyshowing supportfor Florida Gov. Ron DeSantis, who signed the controversial “Parental Rights in Education” bill, denounced asthe “Don’t Say Gay” law, in March.
