and have called it quits after dating for only a few weeks.
Some people are speculating that both the stars were just causally dating each other, but according to some sources, Perry is very upset and probably has her heart broken, again.
Multiple sources have confirmed that it was Mayer who dropped the breakup bomb on Perry.
Even though both the singers had not officially confirmed their relationship, word still got around after they had been seen together multiple times. Even their reps always used to dodge the question of whether both of them were actually dating each other.
According to some sources, it was John Mayer who approached Katy Perry for the first time and she kept putting him off. Mayer is known to be a playboy and has quite a tainted reputation in this regard. So when Mayer approached Perry, he assured her that he was a changed man and that is how she eventually gave in.
Perry and Mayer were first spotted together making out at a friend's party on June 9. Then they went to Chateau Marmont to spend the night there. Perry was then seen spending nights at Mayer's and things had been going quite hot and heavy between them until now.
"John did a real number on Katy," a source told RadarOnline.com. "She held off from his advances for the longest time, but he laid on the charm thick and promised her he was a changed man. She eventually gave in, fell head over heels for him and then - yep - once he had made his conquest, he dumped her."
Now it seems as if Katy Perry and John Mayer are not even on talking terms, as both of them went to a common friend's party and did not even say “hi” to each other. Both of them remained in separate rooms and when they passed each other, they bent their heads down.
