Los Angeles, California - Ariana Grande's reaction to being cast as Glinda in the upcoming movie adaptation of Wicked is quite the tear-jerker.

Let's face it: queen Ari was practically made for the bubbly and "popular" role of Glinda the good witch in the upcoming film version of Wicked the musical.

When the announcement was made, fans across the world praised the incredible casting of Ariana Grande as Glinda and Cynthia Erivo as Elphaba, her green witch counterpart.

The news was immediately posted on the Dangerous Woman singer's IG with the caption, "thank goodness" - an ode to one of Glinda's songs in the original Broadway musical.

But now, her brother Frankie has spilled the beans on Ariana's audition process, and what happened the moment she found out she'd be officially a part of the movie.

And it's priceless.

Ari's brother Frankie Grande has been a supporter of his sister doing the film project since day one, as the two have grown up with theatrical backgrounds and both have starred on Broadway.

He told E! News in a new chat that he was by his sister's side throughout the film's auditions and even helped her practice lines.

"She worked very, very, very, very, very hard on the audition process and she would let me in afterwards and tell me how each one of them went," he said.

She has continued to express her gratitude for the role by keeping fans updated during filming. Her posts have shown her singing songs from the musical on TikTok and hinting at her love for the role with Instagram posts inspired by Glinda.
