Ariana Grande is already prepping for her role in the upcoming movie adaptation of "Wicked."

On Saturday, the "7 Rings" singer watched a showing of the Broadway musical "Wicked" at the Gershwin Theatre in New York City after she was cast as Glinda in the upcoming John M. Chu-directed feature adaptation.

Grande gushed over the performances of the musical's stars, Lindsay Heather Pearce and Brittney Johnson, posting on her Instagram Story that they "were so very, very brilliant."

"Truly an honor to see and hug and hear and witness you both," the pop star continued. "I am weeping! Still! Words simply do not suffice. Everyone was so remarkable. I feel so deeply thankful to have experienced this tonight. Floating!"

In her post, Grande included a photo of the play's Land of Oz map that adorns the stage curtains. She also posted a clip of herself looking up at a framed poster from the original Broadway run, which features Kristin Chenoweth as Glinda.

Chenoweth, 53, shared Grande's post on her own Instagram Story and wrote: "I love you, baby girl."

The "Bang Bang" singer then shared Chenoweth's Instagram Story to her own account and responded, "I love you most!!!"

Grande and Cynthia Erivo were cast as Glinda and Elphaba, respectively, in the upcoming "Wicked" movie musical. When the casting was first announced, Chenoweth congratulated the 28-year-old pop star on Instagram.

"I'm not sure if I've ever been this proud. From the very first day I met you (swipe to see!!), you were destined for this role. Congratulations @arianagrande! The best Glinda you will be with @cynthiaerivo by your side," Chenoweth wrote. "I love you!!"

Chenoweth posted a black-and-white throwback photo of herself posing backstage with a younger Ariana during the show's early days. The actress also shared a 2011 tweet in which Grande expressed "how badly I want [to] play Glinda at some point in my life! #DreamRole."

Erivo and Grande announced their respective castings via their Instagram accounts in November 2021.

In her post, Grande shared a photo showing her reaction to the news that she will star in the upcoming film as well as a snap of a bouquet of flowers she received from Erivo, which included a card that read: "Pink goes good with green. Congratulations, Miss A, the part was made for you. I look forward to sharing this musical journey with you."

Erivo, meanwhile, shared screenshots of her video call with Grande along with a photo of the bouquet of flowers she received from the "Thank U, Next" singer. It included a card with the message, "Dear Cynthia, honored doesn't even begin to cover it. I cannot wait to hug you. See you in Oz. All my love, Ari."

"Wicked" debuted on Broadway in 2003 with a cast that featured Chenoweth, Idina Menzel as Elphaba and Joel Grey as the Wizard. The original production won three Tony Awards and six Drama Desk Awards, as well as a Grammy Award.
