Sly Stallone got fed up with fellow movie hardman Bruce Willis after the “Die Hard” star allegedly dragged his heels over “The Expendables 3.” Stallone unleashed on Twitter, saying that Willis had been booted from “The Expendables” franchise, adding, “greedy and lazy . . . a sure formula for career failure.” Willis played a CIA agent in the first two incarnations of “The Expendables,” written by Stallone, who also directed the first movie. A source tells us, “Sly puts everything into his movies. He gets frustrated if he feels others are not doing the same.” Flacks at Rogers & Cowan, who awkwardly rep both stars, told Page Six yesterday there would be no comment. Willis showed no sign of being upset at the Sayers Club Tuesday night to see eldest daughter Rumer’s performance at the Hollywood music hall.
