The heated “feud” between Matt Damon and Jimmy Kimmel rages on. Even on a red carpet, it’s hard for the pair to keep things civil.

Damon walked the carpet at the premiere of his new film, Air, at the Regency Village Theatre in West Hollywood on Monday, and spoke with Et’s Kevin Frazier about his long-standing (supposedly) bitter rivalry with the late-night talk show host.

When asked if he’d ever be interesting in burying the hatchet and just moving on, Damon exclaimed, “No, no, he’s an a**hole. Why would I ever do that?”

“He’s a terrible human being,” Damon stressed. “He’s a terrible human being. He’s a demonstrably bad man.”

Kimmel — who has long kept up the hilarious pretense of seething disdain with his longtime friend — walked the carpet behind him, and Damon took the opportunity to take a jab at the host.
