John Mayer

For someone who likes to call his relationship "private" when asked about it, John Mayer had no problem gushing about Katy Perry onstage in front of a slew of cameras this weekend. It's almost like he had an album to promote or something!

A great number of Katy Perry's biggest hits were co-written with the same woman,Bonnie McKee, who's now launching a career as an artist in her own right.  Bonnie's working on Katy's new album as well, and she say's that it'll definitely be a change from Katy's last disc, Teenage Dream...

Now that Katy Perry and John Mayer are back on again, the 'Fireworks' songstress is laying down some ground rules for the 'Paper Doll' singer-songwriter. If he wants to date Perry again, he's got to follow some dang guidelines!

Katy Perry and John Mayer reportedly spent Memorial Day together at a barbecue at Katy's house, and the on-again, off-again couple appear to be back on...for now.

Taylor Swift doesn't talk specifically about her love life to the press, but that doesn't mean she won't authorize someone else to spill the beans.

Katy Perry and John Mayer sent the rumor mill into overdrive when Katy emerged from the couple's Valentine's Day dinner at Vincenti Restaurant in Los Angeles sporting a heart-shaped ruby ring on her left hand.

Now that Katy Perry has publicly referred to John Mayer has her boyfriend, it's John's turn to speak publicly about Katy.  Asked by Rolling Stone magazine how the relationship has been for him, John says, "It's been . . . I mean, I'm quite happy. I'm happy in all aspects of my life. I'm very happy in all aspects of my life."

On-again, off-again musical couple Katy Perry and John Mayer celebrated his 35th birthday by enjoying lunch in New York City. The couple that spends bdays together and chows down together should stay together, right? You never know with this fickle, makin' up and breakin' up couple.

John Mayer once referred to his ex Taylor Swift writing about their relationship and their split in a song as “cheap songwriting” but we’re going to call his method of dumping Katy Perry (after a very short and public romance) a cheap move. Mayer reportedly broke up with the ‘Wide Awake’ singer via email.

When Taylor Swift's album Speak Now came out, everyone assumed that the song "Dear John," a vicious swipe at a lover who "messed with"  her, was about John Mayer. Though she never confirmed it, John Mayer thinks it's about him, too, and he's not happy about it.
