John Mayer

Katy Perry makes her debut as a Vogue cover girl in July, playing a high-fashion siren/farmer's daughter (we think). But in the accompanying interview, she talks about the loves of her life: ex-husband Russell Brand and on-and-off boyfriend John Mayer.

John Mayer has a new song out called 'Paper Doll' that may be a response to Taylor Swift's break-up song about him called 'Dear John.' And while John doing a song about Taylor who did a song about him is all very meta, even more confusing is the fact that Mayer teamed up with Prancercise creator Joanna Rohrback to demonstrate how to properly "romancercise" to the new song. We have stared

This is the breakup that just won't end. Even though Taylor Swift and John Mayer haven't been together for over three years, they keep fueling the gossip fire by writing songs about each other.

After they were seen canoodling at a party over Memorial Day weekend, rumors immediately ignited that Katy Perry and John Mayer were back together. While this was a rude assumption that assumed neither of them had the self-control to maintain a platonic friendship, well ... it looks like it's probably true.

Katy Perry has been a busy lady. In between platonic wedding-watching with Robert Pattinson, she managed to throw an A-list Memorial Day party -- and one of her invited guests was off-and-on boyfriend John Mayer. Cue the "oh no, not again" eye rolling.

Memorial Day Weekend has come and gone and along with it many backyard barbecues with friends and family. Katy Perry also had a Memorial Day BBQ and who was in attendance? Well, none other than her ex-boyfriend John Mayer!

Are you ready to rock out at the largest free concert in America?! We bet you are! John Mayer, Demi Lovato, Ne-Yo and J. Cole are all set to perform at the 2013 Philly 4th of July Jam!

John Mayer isn't just touring this summer for the first time since his throat surgery -- he's also promising a new album!

Throat surgery seems to have gone very well for John Mayer. It gave him time to think about his life, prompting him to admit his wrongdoings to his many spurned ex-flames (even the ones who can't seem to get over him already). And now he's expanded his humanitarian efforts to those who really need it -- by helping fix up some veterans' homes in Louisiana.

We've said it before and we'll say it again-- hell hath no fury like a Taylor Swift scorned. The ACM Awards were kind of a rough night for T. Swizzle who was none too happy that her ex John Mayer was also in attendance.
