Demi Lovato will cap her comeback year in grand fashion:
The singer has been tapped to co-host MTV's NYE in NYC 2012, its annual, televised New Year's Eve celebration. She'll MC the festivities along with Teen Wolf's Tyler Posey.
The event gets underway at 11 p.m. EST on December 31 and while Lovato and Posey count down the moments until midnight, they will introduce performances by Selena Gomez, Mac Miller, J. Cole and Jason Derülo. Demi is also expected to bust out with a song.
Billed by the network as the "ultimate dance party," MTV will beam out this special from its Times Square studio, directly above the millions expected to gather in New York City for the famous ball drop.
