Kristen Stewart is Sad. Like, Really Sad.

Unfortunately, I don't even mean "she is crying a lot and eating way over her caloric limit." I mean she is straight up pathetic. She and Robert Pattinson broke up very publicly about a month ago... yet she was seen on Monday wearing Robert's hat and backpack. Oh, and she was also wearing a ring he gave her. While wearing a Baltimore Orioles cap and backpack which belong to Pattinson, and a gold ring that he gave her. I think she might be capable of killing someone:

"Rob's not impressed by the photo of Kristen, and he's not sure what she's trying to prove," a source close to the situation exclusively told Radar.

"He's been doing his best to push through this, promoting his movie and everything while still trying to figure out where he and Kristen stand. With these photos of her wearing his hat, backpack and ring, it's just got him wondering what kind of mind games she's playing.

If I know anything about getting felony-level clingy after a breakup (and I do) ... this kind of behavior isn't making Kristen Stewart more appealing.
