— Jeremy Renner (@Renner4Real) May 10, 2015In April, Renner made headlines when he made a self-described "tasteless joke" about Black Widow during an interview with Digital Spy, calling the comic book character a "slut" for not ending up with his character, Hawkeye, at the end of The Avengers: Age of Ultron.
Costar Chris Evans, 33, who plays Captain America, then chimed in, calling the character "a complete whore," who "flirts with everybody."
Both actors immediately apologized after the interview surfaced online, with Renner saying it "was not meant in a serious way."
Two weeks later, Renner, touched on the interview again during an appearance on Conan.
"It was a joke – off-colored or whatever – but yeah, I'm unapologetic about a lot of things ... mind you, I was talking about a fictional character and fictional behavior," he told host Conan O'Brien.
