In July 2019 it was announced that Brenda would be playing the lead role of Delores Van Cartier in the upcoming UK Tour and West End revival of "Sister Act: The Musical", with Whoopi Goldberg confirming that the part was being revised specifically to allow Brenda to play the role after being rejected from the original UK casting for being "too old". (The original versions had Delores as a 23-year-old, contrary to the older character portrayed in the movie from which the musical was based.)
