JTIMBERLAKEBIEL091507_001.jpgJustin Timberlake jtbielslap.jpgWe were initially happy to see Justin Timberlake and Jessica Biel arriving at a hotel together on Saturday night - until Justin decided to change our mood for us, that is!

First, JT dispatched JB to the door by herself, where she was met and hustled inside by Jeffrey Katzenberg. Then, as he sprinted inside, Justin took a swipe at a camera belonging to an X17 photog - keep an eye peeled for Justin's quick swipe in the video below!

Way to go, Justin! That was almost a $6000 mistake -- but of course that's just pocket change for you ...
