Alec Baldwin exploded in rage at a photographer today, grabbing his arm and getting right in his face.
The 54-year-old star started to walk away, but he wasn't finished yet.
Baldwin screamed, "I want you to shut the [expletive] up and get out of here! Leave my neighbor alone!"
Baldwin was enraged because he thought photographers staking out his Manhattan apartment building were annoying a neighbor, who tried to get them to leave. She even put up her hand to block the shots.
He cornered freelance photographer Brian Prahl, who's much shorter than Baldwin's 5' 11''.
Baldwin screamed at Prahl, "Did you hear what I said? You little girl."
The confrontation is the latest salvo in Baldwin's escalating war with the paparazzi that started two weeks ago, when he went after a photographer who encountered the actor as he was getting his marriage license.
On Wednesday, Baldwin was out with his striking 16-year-old daughter, Ireland. Police intervened as Baldwin complained about the daily presence of photographers.
Baldwin told police, "I want to press charges against this guy for stalking and harassment."
On Thursday, Baldwin tweeted, ""Reporters" are stalking outside my house, and following in their car. Only to harass and disturb. If only a meteor would hit that car."
HLN's Jane Velez-Mitchell told INSIDE EDITION, "You don't want to be caught on camera putting your hands on a photographer, and that's exactly what happened. He's a very sophisticated guy, I think he's letting his emotions and sense of righteous indignation get the better of him. This is the price you pay for fame."
Baldwin is set to marry 28-year-old yoga instructor, Hilaria Thomas, this weekend. The ceremony is reportedly scheduled for the old Saint Patrick's Cathedral in Lower Manhattan.
The details are so super-secret, even the guests won't be told where the reception is until the wedding day. His own brother, Stephen Baldwin, said, "I'm going. I haven't been told the location yet."
Judging by his short temper, Baldwin seems to have a bad case of pre-wedding jitters.
