The Wicked release date is just a week away, and in preparation for it, Ariana Grande and Cynthia Erivo have been all over the world promoting the movie musical and talking to all sorts of people.
Both Grande and Erivo were both just as surprised and fangirling over the interviewer being part of something they love so much: Avenue Q. The interaction only got better once Renata left her seat.
I think Ariana Grande might have blasted her microphone out by the sound of her surprised reaction.
Hence why Ariana Grande quipped that she had to share her love for the musical quietly.
