John Mayer

John Mayer may have admitted to Ellen DeGeneres on her namesake show that his now-defunct relationship with Katy Perry was private as they entered and exited it, but some new details have come to light about why the pair split. While the relationship is dunzo, his feelings for her apparently are not.

John Mayer was a guest on 'The Ellen DeGeneres Show' and while he did address his breakup with Katy Perry, he didn't actually say much about it.

If her Twitter is to be believed to be any indication about her emotional status, Katy Perry is seriously bummed about her split with John Mayer -- and she is falling from cloud nine again.

John Mayer, the supposed former BF of Katy Perry, covers the new issue of Billboard, something his ex did at the end of 2012. In the feature, he goes deep and detailed about his vocal issues, which pretty much stopped him dead in his tracks from supporting last year's 'Born and Raised.' But the problems were worse than limited promotional abilities. They were so bad, in fact, that Mayer was faced

More than a year after undergoing the first of two surgical procedures to repair his vocal cords, John Mayer is all healed up and ready to hit the road for his first series of extended tour dates since he concluded his 'Battle Studies' trek in 2010.

Poor Katy Perry. After news broke that her relationship with John Mayer has ended for the second time, her ex-husband, comedian Russell Brand, who has always been so positive and often speaks warmly about his former missus, added insult to injury by saying that the marriage was "a drag." Ouch.

It's dunzo for Katy Perry and John Mayer for the second time.

Simon Cowell doesn't have a judge's panel controversy on his hands with 'X Factor' simply because he doesn't have any judges! With Britney Spears bouncing after a season and L.A. Reid making his exit to return to running his label, and Demi Lovato's future up in the air, he needs to bring in some big names to fill the empty slots. The latest rumor has Katy Perry and her BF John Mayer atop the wish

Finally, something other than Katy Perry's dress-filling boobs is getting some attention. While the singer's fun bags were the talk of the Grammys, the topic of conversation has since switched, thanks to the ring that Perry wore on Valentine's Day. The piece certainly sparked speculation that she and John Mayer are more serious than we thought.

That John Mayer. He used to be such a cad. And so much fun when he opened the hole in his face to spew about his ex-girlfriends, calling them ridic things like "sexual napalm." (Hi, Jessica Simpson!) He's softened in his old age now that he is dating Katy Perry and reportedly rented out the Vista Theatre in East Hollywood to celebrate Valentine's Day with her. Aww!
