Kristen Stewart RIPS PHOTOG — ‘You Don’t Deserve to Breathe the Same Air I Do’

073013_kristen_stewart_x17_launchKristen Stewart tore a paparazzo a new a-hole yesterday  … dropping f-bombs and screaming, “You don”t deserve to breathe the same air I do.”

The video”s intense … Kristen is seen hiding behind a gate, waiting for a ride outside some building in Long Beach, when the photog — not our sources — asks, “Why are you saying f**k off”

Obviously, Kristen was pissed even before the camera rolled … but it”s unclear what took place BEFORE the paparazzo started recording.

But Kristen, who appears like she”s been pushed to a breaking point, unloads, saying, “Because you”re a piece of s**t and you don”t deserve to breathe the same air I do.” That”s just the beginning. It”s crazy. Check it out.
