Just as we started to forget about this couple, they may have broken up! Twilight lovers, Kristen Stewart and Robert Pattinson are on a break! A studio source has revealed that, “Things have been a bit rocky for a while. They both have hectic work schedules, Rob in particular at the moment, and their phone calls were getting fewer and further between. They started to only see each other on set and began to drift apart until a general apathy developed." Apparently Rob is the one with the super busy schedule and he told Kristen that they needed to cool off with everything.
