I don't really know how it works. But I have read a million times that the paparazzi say mean things to celebrities to try to get a reaction from them. Well, it looks like it worked on Nick Lachey while he was on his way out of LaGuardia Airport with Vanessa Minnillo. Click here to watch the video.  The photographer is claiming that Nick said, "I'm going to f**king kill you if I ever see you again!"
That doesn't really SOUND like Nick does it? But then again, maybe he has had it with all the bad press Vanessa is getting.
