With the New Year fast approaching, Z100 was quick to announce line-up for its annual Jingle Ball concert. It was Demi Lovato, the first artist confirmed as performer for the forthcoming event, who was appointed to reveal the musical guests. She unveiled them at official kick-off party recently.
Lady GaGa has been chosen as a headliner at the star-studded gig. The "Born This Way" hitmaker will make merry the forthcoming concert along with Kelly Clarkson, David Guetta, LMFAO, Pitbull, Foster the People, Gym Class Heroes and Hot Chelle Rae.
Beside announcing performer list, Demi also performed at the kick-off party which took place at NYC's Aeropostale Times Square on Friday, October 21. Her set included her first "Unbroken" single "Skyscraper" and a cover of Lil Wayne's ballad "How to Love".
Z100's Jingle Ball is not the only concert GaGa has on her plate for end-of-year schedule. The Mother Monster has also been tapped to sing at Times Square for "Dick Clark's New Year's Rockin' Eve with Ryan Seacrest 2012". She will be joined by Justin Bieber for this celebration.
