MTV's NYE in NYC 2012

Among the many celebrations going down in the Big Apple, MTV played host to its "NYE In NYC 2012" special in Times Square on Saturday night, December 31, hosted by "Teen Wolf" star Tyler Posey and Demi Lovato.

The event lit up the Times Square studio and found Lovato herself, Selena Gomez, Mac Miller, J. Cole and Jason Derülo performing their way into 2012 in front of a sea of energetic fans.

Lovato played double duty as the clock counted down to midnight when she kicked off the star-studded performance event with her new single, "Give Your Heart a Break." Dressed in a black corset and skirt, the former Disney starlet belted out the tune, offering fans big notes and vocal runs.

Jason Derulo turned up the dance even more when he took the stage for "It Girl" and "Don't Wanna Go Home".

Mac Miller topped off his successful 2011 with a comedic performance of his hit single "Party on Fifth Ave," in which he recreated the tune's retro clip.

Soon after, J. Cole continued to rep for rap with "Work Out." Walking back and forth in a path made by fans, the MC spit the feel-good song as the audience simultaneously waved their hands in the air.

Wrapping up the show was Selena Gomez, who screamed the countdown to 2012 and kicked off her first performance of the new year with a medley of "Love You Like a Love Song" and "Hit the Lights."
