All eyes are on the seemingly budding romance between singers Katy Perry and John Mayer, who’ve been seen around town in Hollywood hotspots like the Chateau Marmont, which is where celebs are “supposed” to go to have some peace and quiet out of the public eye, yet they are always photographed there because the paparazzi know about it. However, the relationship between the two might not be as new

Awk-ward! Exes John Mayer and Taylor Swift uncomfortably ran into each other at a Hollywood hotspot on Tuesday night.

John Mayer has never been one to mince words in the press, especially about his exes, like Jessica Simpson and Jennifer Aniston. But turns out Mayer doesn’t like it when the shoe is on the other foot.
