Alec Baldwin was reportedly involved in a violent scuffle with a photographer today.

The "30 Rock" star was leaving the New York City Marriage License Bureau after allegedly obtaining a license to wed fiance Hilaria Thomas, when he approached a lens man who was nearby.

According to the New York Daily News, photographer Marcus Santos was standing with two other photographers when Alec approached them in a temper.

"He was looking mad," Marcus told the publication. "He said, Step back, step back.' I said, We're moving back.'"

When Alec allegedly "grabbed" a second photographer, Marcus told the Hollywood star to leave him.

"I said, Don't touch him.' I knew he was going to attack me. I stepped back, and he kept coming," he recounted. "He comes after me, starts shoving and punching me one time, right in the chin. And then he started shoving me, and pushing me. Then he goes the other way."

Alec reportedly left without saying a word. His 28-year-old fiancee was not with him at the time.

Alec took to Twitter to describe his version of events.

"A photographer' almost hit me in the face with his camera this morning. #allpaparazzishouldbewaterboarded (sic)," he wrote.
