The super popular group Mindless Behavior was on hand for the 2011 Z100 Jingle Ball, held Friday night (Dec 9) at Madison Square Garden in New York City.

As a part of the annual event’s festivities, the guys — Princeton, Ray Ray, Roc Royal and Prodigy — hung out with other celebs in the Z100 & Reebok Classics Artist Gift Lounge and also performed during the Coco-Cola All Access lounge pre-show at the Hammerstein Ballroom, located inside MSG.
