Three years after “Dear John,” it seems that John Mayer is finally giving Taylor Swift a taste of her own medicine with his new single, “Paper Doll.” Let’s check out the lyrical allusions…

So much for needing a heartbreak coach! According to reports, Katy Perry and John Mayer are back on. The two first began dating last summer, but after a couple of brief splits and a few engagement rumors, they finally called it quits in March. At the time, their breakup was credited to their equally hectic schedules — but that’s all water under the bridge now.

John Mayer has never been too secretive about his relationships, but when it came to Katy Perry he kept things on the down low. The couple rarely acknowledged that they were dating and for them, the red carpet seemed to be off limits. Despite his coy ways, John talked about not talking about their split during a recent appearance on The Ellen Degeneres Show.

Several sources are reporting that Katy Perry and John Mayer have split… for the second time. The two singers started dating in June of last year, but they parted ways after just two months. One month later, they decided to give it another go, with rumors circulating last month that the two had even gotten engaged. But alas, they have apparently once again called it quits with sources claiming that it was their busy schedules that ended the courtship. But for all you fans out there hoping Jhn isn’t another “one that got away,” there may still be hope!
