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.
Ed Sheeran and John Mayer performed 'Thinking Out Loud' at the 2015 Grammys and the PopCrush editors were literally weeping from the beauty of it all.
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.
John Mayer was asked by TMZ on the idea that his ex Katy Perry will be writing songs about him. "You're supposed to write songs. You're just not supposed to tell everyone you're doing it."
