The singer told BBC 6 Music that she has "butterflies in my stomach" about the production because she has never done anything like the play before.

"I haven't heard that for sure but I just always thought it would."
She added that she was "very honoured" when her music for the adaptation won the Drama Critics award in Los Angeles.
