Z100’s Jingle Ball 2010 presented by H&M kicked off on Friday, December 10 at Madison Square Garden in New York City with a number of big stars in attendance. Fresh from their dating rumor, Selena Gomez and Justin Bieber made appearances that night, but they hit the red carpet separately. Although at one point Justin did pose with Kim Kardashian.

Enrique Iglesias made a certain girl’s heart all a flutter when he brought her up on stage and sang to her. While Katy Perry was dolled up in a toy solider costume and was joined onstage by three Santas.
