"Absolutely not, don't do it. I want to be Glinda, not Ariana Grande playing Glinda," the singer, who stars in the Universal movie adaptation of the musical, said.

When it came to her take on Glinda, Ariana Grande didn't want to stray too far from the original Broadway musical version of 'Wicked'.

Wicked composer Stephen Schwartz has revealed that Ariana Grande refused to make a suggested change to a classic song.
