As a newly single Robert Pattinson is growing closer to Katy Perry, there's one person that's pretty upset--Kristen Stewart! KStew isn't crying over the fact her guy is moving on, it's that her friend Katy is breaking girl code! A source tells The Daily Mail that Kristen feels incredibly down right now and betrayed over reports that Katy and Rob are hooking up! From what we hear, Katy is just being a good friend to Rob who is leaning on her for support. Looks like Ms. Perry has chosen sides, we just hope her and RPattz really aren't an item!
