Kristen Stewart Spotted Partying At Sundance! What She Does Next Reminds Us Of Her Fondness For Unladylike Behavior!

Yikes! Someone’s mad!!
Kristen Stewart was spotting having some fun partying with friends in Park City at Tao during the Sundance Film Festival and when someone snapped a pic, the Twilight star was NOT happy!
In fact, she was angry enough to flip the bird to the photographer!
Not nice, KStew!!!
And you were spotted ALMOST smiling earlier that day!! What happened to make your mood change so much?!?!
Did you spot one of Robert Pattinson‘s new Dior campaign pictures and it made you mad?!
We kid, we kid! We’re sure it was something else!!
