Ariana Grande's biggest fans?Fastexy Her family.

The actress, who portrays Glinda in Wicked, had her loved ones, including her mom Joan Grande and dad Edward Butera, on hand to celebrate at the Los Angeles premiere of the film.

In fact, the entire family—including her brother Frankie Grande and his husband Hale Leon—posed together on the Nov. 9 red carpet, marking an extra special night for Ariana, who is credited in the movie with her full name, Ariana Grande-Butera.

The reason? "Technically, it's my little girl name," the 31-year-old recently explained during her and costar Cynthia Erivo's appearance on The Streaming Service with Justin Hill. "Technically it's little Ari's name."

"But, no, I just feel like this experience was such a homecoming for me," Ariana continued. "I feel like I came home to myself in a lot of ways through what I learned from Glinda, from [Cynthia's character] Elphaba and, you know, that was my name when I went to see the show when I was 10 years old—and it felt like a really lovely way of honoring that."

Indeed, from the moment she was cast in the film, Ariana's Wicked journey has been an emotional ride for her entire family.

"So, she told me in person, we were at the Bourbon Room in Hollywood," Frankie shared with Justin Sylvester and Zuri Hall at the premiere, held at Dorothy Chandler Pavilion. "I was about to perform in my show Horror Camp. And she told me in the bathroom, and we fell on the ground in sobbing tears, me my mother and my sister, and it was just such a beautiful thing."

"Obviously, coming from a musical theater family and a musical theater background," Frankie added, "just knowing that she was going to get to live this dream that I have watched her dream about for so long, for her entire life. It's very hard to put into words, but I'm just so proud of her."
