'You're A Piece Of S***': Kristen Stewart Hits Out At Paparazzi Amid Robert Pattinson Questioning

Kristen Stewart was not a happy lady when taking a break on the set of new movie Camp X Ray yesterday and hit out at the paparazzi pack who were waiting for her telling them "you're a piece of sh**," when asked why she was unhappy according to a video posted online.

The actress is under constant siege from the pap squad, especially following her break up with Robert Pattinson earlier this year, who follow her every move but usually manages to ignore them.

Clearly though, the Twilight beauty wasn't in the mood to see them yesterday and hit out as she waited to get into her car.

In the video, posted by X17Online and claiming to have been taken by one of their photographers, someone can be heard asking the actress, who is hiding behind a screen: "Why you saying f**k off," to which she can be heard replying: "Because you're a piece of s**t. You don't deserve to breathe the same air I do."

The actress can be then seen getting into a car as the photographer questions her about her romance with Robert Pattinson, asking if they were "back together" or if if she was "dating anyone new".

Unsurprisingly, she didn't answer, though looked stoney faced at the mention of her ex. The couple broke up after four years together in May this year and with constant speculation about whether they're dating anyone new we're not surprised she wasn't pleased about the snapper turning up to the set of her new movie.

We wonder if Kristen was feeling extra sensitive after Katy Perry spoke out about her alleged romance with the actor? The Firework star spent alot of time with the hunk after he split with Stewart and in an interview with Elle Magazine, the 28 year-old spoke candidly about contacting Kristen to assure her she wasn't being anything more than just a friend.

"I sent her a text message saying: 'I know you've seen all this stuff but you know I would never disrespect you. I'm not that person.'" she revealed in a new interview.

"'I'm just trying to be a friend to him but it is unfortunate that I do have a set of t*ts."'

Kristen's had a difficult few months with the photographers since the split and there's definitely no love loss between the star and her stalkers. In June, "I heart Rob" was written in dirt on her car while she was visiting an LA film studio, to the amusement of the paparazzi.
