James Gandolfini punches a fan at LAX!

Wow, did someone not get their hot towels and peanuts on their flight or something?!?!?

The star was caught in an altercation at JFK airport yesterday after being pursued by an overzealous autograph hunter who declared himself a big fan of the actor.

The affection was clearly not mutual, with an irritated Gandolfini grabbing the man by his collar and punching him, claiming he came to close to his girlfriend Deborah Lin.

At one point after James roughed up the guy, the obviously flustered autograph hunter yelled out “I’m just trying to find out how to be a Soprano!” and James quipped back “well, that’s how you do it.” They eventually kissed and made up and James took a picture with the guy, but dayum. Take a chill pill!
