Watch Performances From Demi Lovato, Selena Gomez, Mac Miller + More From MTV's 'NYE In NYC'

So while I was at an overheated and overcrowded New Year's Eve party in the depths of Brooklyn (with no New Year's kiss, FYI), MTV was throwing "NYE In NYC 2012," a huge-ass party cohosted by "Teen Wolf's" Tyler Posey and Demi Lovato, featuring live performances by Demi, Selena Gomez, Jason Derulo, Mac Miller and J. Cole. And even though I missed it IRL, I can relive the night with these performance videos. Yay, internet!

Our girl Dem (who, by the way, looked COMPLETELY STUNNING in her NYE ensemble) took the stage to perform her brand-new single, "Give Your Heart A Break." Backed by a full band, not only did Demi deliver a completely heartfelt performance, but girlfriend was singing VERY LIVE and she sounded VERY incredible.

Jason Derulo hit the stage to perform his ode to the perfect lady, "It Girl," followed by his club banger "Don't Wanna Go Home." (The most important part? HIS SHIRT WAS OFF.) MTV Push alum Mac Miller was jumping tirelessly during the entire performance of "Party On Fifth Avenue," and unsurprisingly, J. Cole was as chill and dope as ever while performing his hit "Workout." Selena Gomez closed out the night and looked fully festive in a crystal-encrusted gown as she sang "Love You Like A Love Song" and her current single, "Hit The Lights."

So yes, in case anyone was still confused about it, MTV's New Year's Eve celebration was, in fact, significantly better than yours.

+ Watch Demi Lovato perform "Give Your Heart A Break" during MTV's "NYE In NYC," and check out more performances from Jason Derulo, Mac Miller, Selena Gomez, and J. Cole after the jump.
