John Mayer

If the matching patriotic shirts from Fourth of July didn't convince you that John Mayer and Katy Perry were an item and "on" again, perhaps this video of Mayer, revealing how and why he fell in love with "my Katy" while performing a 'A Face to Call Home,' will...

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!

When John Mayer performed on 'Today,' there were a lot of questions about his songwriting inspiration. Namely, was his new song 'Paper Doll' about a certain Taylor Swift? Mayer's answer -- or lack thereof -- was pretty telling.

Although John Mayer was recently spotted celebrating Independence Day with ex Katy Perry, it’s been awhile since we’ve seen him on TV. However, the charming singer made a comeback this morning (July 5) on NBC’s ‘TODAY,’ where he performed a few songs on the scenic outdoor stage and filled us in on his recovery from his vocal cord procedures.

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?

After two splits in under a year, Katy Perry thinks the third time with John Mayer will be the charm. To help hedge her bets a little, though, she's established some ground rules that we're sure he'll follow for a week or so.

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!

Seems Katy Perry just can't stay away from John Mayer -- not only did she recently admit to Vogue that she's still "madly in love" with the singer, she was also spotted with her lips on his lips this weekend.

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.

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.

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.
