Making the most of his Friday night (January 7), John Mayer was spotted at the Roger Room in Los Angeles.

Joined by comedian Jeffrey Ross, the “Waiting on the World to Change” singer looked snazzy in a black suit with a white button-up shirt.

Making for quite the star-studded affair, a slew of celebs turned up at The Cosmopolitan Grand Opening and New Year's Eve Celebration in Miami, FL on Friday night (December 31).

Having been doing a good job avoiding the spotlight these days, John Mayer was spotted out for a wintertime walk in New York City on Monday afternoon (December 6).

Bundled up as he braved the chilly climate, the "Gravity" singer listened to his headphones while slowly but surely making his way down the Big Apple streets.
