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...

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.

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.

In the battle for Katy Perry's heart, right now there are rumors of a Robert Pattinson romance as well as a John Mayer reunion in the works. But Perry's pals are rooting for only one of those guys. Which one?

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.

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

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.

Katy Perry has been a busy lady. In between platonic wedding-watching with Robert Pattinson, she managed to throw an A-list Memorial Day party -- and one of her invited guests was off-and-on boyfriend John Mayer. Cue the "oh no, not again" eye rolling.
