John Mayer has reportedly dumped Katy Perry after only weeks of dating.
The infamous ladies man proved he hasn't changed his ways when he brutally dumped Perry despite wooing her with promises of him being a reformed man.
"John did a real number on Katy," Radar Online quoted a source as saying.
"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," the source said.
According to a source, the former couple were spotted at a mutual friend's dinner party on Tuesday night but completely ignored each other.
"It was so weird! Katy stayed in one room the whole night and John stayed in the other and when they passed each other they both just kept their head's down," an insider said.
"It was like they had this incredible animosity for each other and everyone else at the party could feel it. You could cut the atmosphere with a knife. It was all incredibly high school!" the source added.
Despite the fact that the cold front was putting other party guests on edge, both stayed until after midnight and continued to ignore each other the whole time, the source said.
Perry got busy chatting to a blonde model in a hipster Fedora, while Mayer talked to a busty brunette.
