Kristen Stewart lashed out at a paparazzo during an outing in Los Angeles on Monday (29Jul13), unleashing a foul-mouth tirade while hiding behind a trash can. The often shy Twilight actress confronted a videographer who was filming her out and about with her dog, and hurled a string of expletives in his direction before saying, "F**k off. You’re a piece of sh*t… you don’t deserve to breathe the same air I do.” She then refused to come out from behind a screen covering a number of industrial garbage containers until an assistant arrived to rescue her in a car. Stewart has made no secret of her hatred for the media attention in her life, especially after she was caught on camera kissing her married Snow White & The Huntsman director Rupert Sanders, while she was dating her Twilight co-star Robert Pattinson. The publication of the kissing shots led to the breakdown of her romance with Pattinson.
