Dean McDermott was not excited about a certain photographer hanging outside his home, and he didn't hesitate to confront the guy!

It seemed things were going well during Dean's discussion with the random camera guy, until something ticked McDermott off and he walked away, flipping the photog the bird as he left.

While reality stars McDermott and Tori Spelling usually love the cameras, they've been a bit shy since the pregnant 90210 star got into an accident because of "camera attention".

Apparently Tori was running from the photogs when she got in her crash, but it's kinda hard to imagine Tori and/or Dean ever running from the cameras!
