They might have been friends once upon a time, but Katy Perry has never forgiven Kristen Stewart for the scandal behind her breakup with Robert Pattinson.
Rob and Kristen might be on speaking terms, but if Perry had anything to do with it - all ties between the former couple would be severed.
A sneaky anonymous source told Lifestyle Magazine that;
Katy has told Rob that she thinks it's a really, really bad idea for him to reunite with Kristen. Katy warned him that Kristen will end up hurting him again
The pop starlet has been best of friends with Robert Pattinson for years now, but the rumors that she is actually secretly in love with the 28-year-old actor have never gone away.
Perry could just be looking out for her good pal, but speculation is rife that Katy wants to keep Rob away from Kristen so she can make a move on him...
Do you think Robert Pattinson and Katy Perry will ever get together?
