“Transformers” actor Shia LaBeouf finally addressed his long-rumored feud with former “Orphans” co-star Alec Baldwin on Monday.

During a Monday night interview with “Late Show” host David Letterman, Shia LaBeouf acknowledged that his rocky relationship with the “30 Rock” actor contributed to his dismissal from the Broadway play “Orphans.” Baldwin had been slated to be his co-star.

Letterman wasted no time in questioning LaBeouf on his firing, alluding to reports that the 26-year-old actor had feuded with Baldwin and pointedly asking, “What did you do to him?”

"He's a good dude, and the show is terrific. I got nothing bad to say," LaBeouf responded. "I'm pretty passionate and impulsive, and he's a very passionate individual as well, and I think that impulsiveness and that passion make for some fireworks."

Next, the “Late Show” host, who admitted that he considered Baldwin to be “such a good friend, not just to me, but to the ['Late] Show,'” inquired about the possibility of an amicable reunion between the two actors.

“I think that would be a tough one to pull off,” LaBeouf said, amid laughter from the audience. “I mean, I’m all for it.” LaBeouf added that, while the two had argued, “no punches were thrown.”

In February, LaBeouf was removed from the cast of “Orphans” after just one week of production. While the play’s public relations team stated that the firing was a result of “creative differences,” LaBeouf explained that answer as “sort of a business-savvy answer for what actually happened.”

News of LaBeouf’s ongoing disagreement with his 54-year-old co-star surfaced after the younger actor tweeted a series of private emails between himself, Baldwin and “Orphans” director Daniel Sullivan, the Hollywood Reporter reports.

"I'm too old for disagreeable situations. You're one hell of a great actor. Alec is who he is,” Sullivan wrote in one email to LaBeouf. “You are who you are. You two are incompatible. I should have known it. This one will haunt me. You tried to warn me. You said you were a different breed. I didn't get it."

Still, LaBeouf insists that he harbors no ill will toward Baldwin or the cast of “Orphans.” In fact, LaBeouf told Letterman that he sat front and center at the play’s first preview performance.

"I showed up as a fan," LaBeouf said. "Me and Alec had tension as men, not as artists, but as men. In a room, that became hard to deal with.”
