John Mayer

You love who you love, regardless of gender, skin color or religion. That should be the governing principle of life in general -- but it's most certainly the case in the song and video for the John Mayer and Katy Perry duet 'Who You Love.'

Katy Perry has revealed why she and boyfriend John Mayer broke up last spring and the true reason she split with husband Russell Brand in her January 2014 Marie Claire cover. She looks pretty bangin', BTW!

Katy Perry and John Mayer's duet 'Who You Love,' which appears on his album 'Paradise Valley,' will be the singer-songwriter's next single. Since it's a single, it has to have its own accompanying cover art and it features the couple posing in romantic fashion.

Even though Katy Perry's first marriage ended in divorce after only 14 months, the singer's relationship with reformed Lothario John Mayer is going so well (despite that hiccup this past spring), that sources say it's pretty certain that they will get engaged.

Katy Perry and John Mayer are getting super serious, but as anyone who's followed their tumultuous relationship knows, they've had quite a few ups and downs -- including quite a few splits -- in between. Thankfully, though, those are behind them ... and they even inspired Perry's smash hit, 'Roar.'

Off and on couple John Mayer and Katy Perry are firmly back on -- possibly permanently, if he has anything to say about it, because some sources are saying he's asked her to marry him.

We all knew Katy Perry and John Mayer were getting serious -- but who knew they were getting serious so fast? Sources say that John Mayer have already popped the question to Perry ... and he didn't get the response he'd hoped for.

John Mayer and Katy Perry are back together in a big way. It's not only good for their careers (they keep gushing about one another to the press to promote their new albums 'Paradise Valley' and 'Prism'), but also for their hearts. Turns out, Mayer is even considering taking the next step with Perry. What's that step?

Niall Horan of One Direction had a lot of conflicting emotions this week. Not only were he and his bandmates nominated for a bunch of MTV Video Music Awards, but he also got to hang out with his idol, John Mayer -- and he was also disturbed in his sleep by eager Directioners.

John Mayer has a confession of his own about that heartfelt, confessional duet with Katy Perry: It almost didn't happen!

John Mayer loves Katy Perry -- and he also loves her massive new single, 'Roar.' The 'Paradise Valley' crooner couldn't stop bragging about his lady love's new song, as well as his collaboration with her, 'Who You Love.'

Katy Perry and John Mayer got back together just in time to promote their new albums. Isn't it great when romance is so convenient? The duo each have records coming out soon, and a track from Mayer's 'Paradise Valley,' called 'Who You Love,' has hit the web -- and it features none other than his on-again off-again love.

Katy Perry admitted to being madly in love with John Mayer in her Vogue cover story earlier this summer, despite being broken up at the time. They were seemingly reunited on Fourth of July and now, they get romantic on the song 'Who You Love,' a slow-burning, 'early '80s-inspired soft rock duet.

A random encounter with newly-reunited couple John Mayer and Katy Perry in a New York City guitar shop last week brought one lucky fan much more than just a great photo: Mayer actually bought the aspiring young musician a guitar on the sly.

John Mayer has really turned his act around, and his latest "awww"-worthy deed might just be his kindest act yet.

What the what? These two lovebirds are moving at lightning speed! Not only have Katy Perry and John Mayer reunited (and it feels so good!), but there are now reports circulating that they are moving in together. *Gasp!*
