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.

In our least favorite couples trend, recently reunited duo Katy Perry and John Mayer showed off their patriotism in matching stars and stripes outfits. Blergh. Remind us again why it's disrespectful to let a flag touch the ground, but it's totally cool to wear it all over your body?

Get excited! John Mayer announced that his new album 'Paradise Valley' will hit stores on Aug. 13!

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.

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.

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.

It's often said that revenge is a dish best served cold -- but as Taylor Swift is finding out, it's also pretty good if you can serve it in front of thousands of screaming fans.
