Caitlyn Jenner filed legal documents on September 15 to change her name and gender. Now, a Los Angeles judge has confirmed the legal transition for the "I Am Cait" star, according to E! News.

Jenner requested her name be changed from William Bruce Jenner to Caitlyn Marie Jenner. When prompted by official forms for the reason behind the name change, she put, "To better match my identity," and signed the documents as Bruce Jenner.

She also requested that her medical history remain private, due to threats she's received since announcing her transgender status.

Jenner previously spoke with Drian Juarez, a representative from the Los Angeles LGBT Center, in an episode of "I Am Cait" about the name-changing process.

"You have to go through the court-ordered process, which has been streamlined a bit," Juarez told her. "Before, you had to have gender-confirmation surgery before you could change your gender marker. There was advocacy done to change that, and now you just have to have clinically appropriate treatment to change your gender marker."

"After hearing all the struggles people go through because they don't have the proper documentation, I realized that I should be a little bit more aggressive in dealing with this issue of my identity," Caitlyn replied. "I think it's time to get that process started."

A day after the official name change, the reality TV star released a photo of herself on Instagram holding a Starbucks cup displaying her new name with the caption, "Happy Saturday!"

Jenner disclosed she was transgender this past April in an interview with Diane Sawyer. The big reveal of her new look and name appeared on Vanity Fair's July cover, after she underwent facial feminization surgery and got breast implants.

Her ex-wife Kris Jenner does not call her Caitlyn, but simply refers to her as "Jenner." The couple was married in 1991 and made their divorce final on March 23, 2015. They have two daughters together: Kendall, 19, and Kylie, 18.
