Alec Baldwin has denied punching a news photographer during a confrontation outside a marriage licence bureau in New York.
"If I had punched him, I would be in jail right now, rightfully so," Baldwin said during an appearance on David Letterman's Late Show.
"I kind of pushed him out of the way because he almost hit me in the face with the camera", he added.
Baldwin's confrontation with New York Daily News photographer Marcus Santos was splashed this week on the newspaper's front page.
Police have confirmed that Santos filed a complaint against Baldwin, saying he was punched while taking pictures of Baldwin and his fiancee.
Baldwin told Letterman the photographer is a master at getting close enough to a subject that the subject thinks he is going to be hit by the camera. "They want you to react," he said.
A New York Police Department spokeswoman says no charges have been filed and that police are investigating.
