A buff John Mayer, who took a stand and urged the Los Angeles City Council to "regulate" the paparazzi, changes gears �" and clothes �" Thursday, heading to the gym for a workout.

People magazine is really one of my fave celeb publications because they take ass-kissing to a whole other level, they toss salad and throw in cheese croutons. Heh. They go to extremes to make nice with celebs in order to get exclusives even if they gotta lie. John Mayer is NOT buff! Zac Efron could kick his ass any day, and he's like 10 years younger. Now that boy is ripped. John's arms only have light definition. Please!
