John Mayer stopped by the H&M Gift Lounge in NYC on Friday before taking the stage for Z100's sold-out Jingle Ball. He shared billing with a handful of other big artists like 2009 all-star Taylor Swift and Idol alums Kris Allen and Jordin Sparks. Now John's off for a few dates on the West Coast before moving on to Europe. The number one selling musician spent the last few weeks hanging out and hitting the gym in the Big Apple as he prepped for his big world tour, and we're sure to get all the details about life on the road from John via Twitter.
