On Monday night, “Late Show” guest Shia LaBeouf was grilled by David Letterman regarding the recent turmoil surrounding his exit from the Broadway show “Orphans” and his spat with former co-star Alec Baldwin.

LaBeouf, who was on the program to promote his new film The Company You Keep, wore a walking cast on his left foot as he stepped onto Letterman’s stage. He quipped, “It’s a fashion statement. I broke the metatarsals on the top of my foot . . . I wish I could say I was wrestling a tiger or something, but I was jumping rope.”

“I got fired, Dave, from my job — I was doing a job out here — and I decided I would start boxing,” he explained of his new hobby. “[Thought] it would be a good thing to do, maybe.”

“Why did you get fired?” Letterman asked LaBeouf, 26, bluntly. “Is this the thing with Alec Baldwin ? … What did you do to him?”

‘I’m pretty passionate and impulsive, and he’s a very passionate individual as well. And I think that impulsiveness and that passion makes for, ya know, some fireworks,’ he told TV talk show host David Letterman.

‘Me and Alec had tension as men. Not as artists but as men.’

“In a room, that became a hard thing to deal with. When you’ve got tension as men, that’s tough till July. It’s cool for increments, but to do that for a long period of time would have been tough.”

“Can I suggest a couple of scenarios,” Letterman said, “Alec went to the producers and said, ‘I can’t take it another day, fire him.'”

“I think that might have been what happened,” LaBeouf confessed.

In response to claims that his firing was due to “creative differences,” LaBeouf said there was a lot more to it.

He remarked, “I think that’s what you gotta say as sort of a business-savvy answer for what actually happened.”

Despite their differences, Shia, who was in the front row for the opening night of Orphans, praised Alec as “awesome.”

The Transformers actor expressed his hope that his current connection with the 30 Rock star is “pretty good” and wished him “good luck.”

Alec recently said that the Lawless star isn’t a genuine theatrical performer and couldn’t handle the rigors of a stage show.

‘I can tell you that, in all honesty, I don’t think he’s in a good position to be giving interpretations of what the theatre is and isn’t,’ Alec remarked, referring to one of Shia’s tweets that said, ‘The theatre belongs not to the great but to the brash.’

‘I mean, he was never in the theatre. He came into a rehearsal room for six or seven days.

‘There are people who are film actors who have a great legacy in the theatre. Some of the greatest movie stars had really serious theatre careers and still do. And many film actors, though, who are purely film actors, they’re kind of like celebrity chefs, you know what I mean? You hand them the ingredients, and they whip it up, and they cook it, and they put it on a plate, and they want a round of applause.’
