Robbie recently joined Hugh Jackman on stage for his London shows of his The Man. The Music. The Show. tour in June.
And Hugh was allegedly so impressed with Robbie's performance, The Sunday Mirror reported the actor wants to have the singer play a part in the sequel.
Hugh wants space to be made for them to do a number and sing and act in his Greatest Showman sequel.
"Hugh and others are staying quiet until deals with Fox Studios are secured, but he is going to be a producer which means he will have a say on the cast. Robbie even doing one number would be fun."
