Posting a photo of De Niro to his Instagram, Rourke, 67, put the “Irishman” actor on blast, seemingly referencing past comments made about Martin Scorsese’s crime drama.

“Hey Robert De Niro, that’s right i am talking to you, you big f–king crybaby,” Rourke began. “A friend of mine just recently told me that a few months back you’re quoted as saying to newspapers ‘Mickey Rourke’s a liar he talks all kind of s–t’. Listen Mr.Tough Guy in the movies, you’re the 1st person that ever called me a liar and it was in a newspaper.”

Rourke, whose alleged feud with De Niro dates back three decades, claimed in September that he was blocked from appearing in “The Irishman” because of De Niro.

“Marty Scorsese, great director, he wanted to meet me for a movie with Al Pacino, Joe Pesci, Chris Walken and Robert De Niro,” Rourke said on the Italian TV show, “Live — Non è la D’Urso.” “The casting person told my manager that Robert De Niro said he refused to work with me in a movie.”

De Niro’s rep, Stan Rosenfield, later responded to Rourke’s allegations.

“According to ‘The Irishman’ producers, Jane Rosenthal and Emma Tillinger Koskoff, and casting director Ellen Lewis, Mickey Rourke was never asked to be in ‘The Irishman’ nor was he ever even thought of, discussed or considered to be in the movie,” Rosenfield previously The Post in a statement, adding De Niro is “aware of these comments.”

Rourke also called De Niro a “punk ass” in Friday’s post.

“Let me tell you something, you punk ass, when i see you i swear to God on my Grandmother, on my brother and all my dogs,i gonna embarrass you severely 100%. Mickey Rourke ‘ as God is my witness,’” he continued.

Rourke and De Niro both appeared in Alan Parker’s 1987 film “Angel Heart.” Rourke claimed he had been snubbed by the actor at the time.

A rep for De Niro did not immediately return Page Six’s request for comment.
