Ben Affleck Sneaks Matt Damon Onto ‘Jimmy Kimmel Live!’ (Video)

He didn’t win the Best Actor Oscar, but at least “The Martian” star made it onto the late-night show

Matt Damon and Jimmy Kimmel have been “feuding” for years, with the late-night host repeatedly “running out of time” to have the actor on the show.

But it turns out all “The Martian” star needed to get onto “Jimmy Kimmel Live!” was a helping hand from his best friend.

In a special post-Oscars episode of the ABC late-night show on Sunday — which is conveniently filmed across the street from the Academy Awards venue on Hollywood Blvd. — Affleck came onto the stage wearing a bulky fat suit.

“What have you got, a monkey under there? What’s happening here?” Kimmel asked as he prodded the “Gone Girl” star’s stomach.

When Kimmel ripped open the jacket, Damon — still in his tuxedo from the Oscars — busted out.

“I just think it’s gone on long enough, I think it is time to bury the hatchet,” Affleck pleaded on behalf of his Boston buddy, with whom he shared an Oscar for writing “Good Will Hunting.”

But Kimmel wasn’t budging: “You are ruining the Oscars show … this is trespassing, I could have you arrested right now,” he threatened. “There was not a plus one on your invitation,” he told Affleck.

“I was nominated for an Oscar and I can’t get on the Oscars show,” Damon marveled.
