When Taylor Swift puts out a song, everyone has an opinion: The music critic, the die-hard fan, the hater (who's gonna hate, hate hate) -- and yes, the person who inspired the track.

Katy Perry and John Mayer were seen, once more, getting cozy during a Grateful Dead show.

Singer, guitarist, and Bozeman, Montana resident John Mayer has tried to make things work out with his on-again, off-again lady friend, Katy Perry. Now sources say that relationship is officially over.

In a new MSNBC interview, JOHN MAYER feverishly disagreed with the rumors that he's ever been a womanizer . . . but did admit that he did had an ego problem. Could the laid back atmosphere of Montana life be bringing him down to earth?

John Mayer guest-hosted 'The Late Late Show' last night (Feb. 4), and of course, he couldn't resist gushing about Katy Perry's epic Super Bowl performance.

Taylor Swift and John Mayer were spotted dining at the Chateau Marmont in West Hollywood.

The 2014 Made in America Festival Philadelphia lineup has officially been announced -- and Kanye West, Kings of Leon and Pharrell are among the biggest names on the list.

Katy Perry has finally and officially confirmed what the world knows and is painfully obvious -- that she and BF John Mayer have split.

Sure, we'd love to hear John Mayer cover his ex Katy Perry's 'Dark Horse' or 'Unconditionally.' But that's not likely to happen, so we'll "settle" for being blown away by his acoustic cover of Beyonce's 'XO.'

If Charlie Sheen is your bro, rest assured he ALWAYS has your back. Case in point: this John Mayer fake Rolex mess. What does Sheen have to do with it and why is he firing insults at Mayer and his music via Twitter? Sit back and we'll tell you.

Ouch! After Katy Perry went on an Aussie TV show to say that she pulled away from Miley Cyrus when the singer tried to slip her the tongue in their kiss-seen-round-the-world because "God knows where that tongue has been," Miley has retaliated, rather meanly, on Twitter.

While Katy Perry sidestepped the direct question about having a boyfriend, her reported ex John Mayer praised the singer for her work ethic during a radio interview.
