i think he isnt; i heard that Michael never took the kids to rehearsals. He wanted to surprise all 3 of them when the tour began. Who knoes; maybe prince & blanket might moonwalk on the stage in one of the scenes xD
idk but my mom told me she saw the commercial 或者 预览 and my mom 说 that she saw this guy with brown hair like Prince holding a microphone 或者 something im all like OMP why didn't u wake me up so i could see it but i hope he does come out cuz if he is im gonna be the first one in line to see the movie and whenever Prince comes out(if he comes out)i will be screaming GO PRINCE!!!!YEA!!!!
