The duo are planning to criticise the controversial religion on the stage and its star follower Tom Cruise is horrified at the idea, reported Contactmusic.
"It's still being written but Tom is concerned he'll be the butt of the jokes. Tom caught wind of their plans and wasn't happy but then realised there isn't much he can do to stop it," a source said.
Cruise was recently praised by business tycoon James Packer, who claims the 'Mission Impossible' actor saved him from a deep depression and helped him join the Church of Scientology.
"And he never asked me for anything, in our entire life. He believed in me when other people didn't. I'm very grateful. I just think he's a very special person," he added.
