All you Little Monsters better mark your calendars, because Mother Monster herself, Lady Gaga, will be headlining the big event. The holiday concert will take place on Friday, December 9, at New York City's Madison Square Garden.
Lovato, who is also hitting the stage at Jingle Ball, helped announce the lineup at the official kickoff party at the Aéropostale store in Times Square, where she also performed. The singer took the stage in front of a crowd filled with her fans (a.k.a. Lovatics) and sang four songs, including her cover of Lil Wayne's "How to Love" and her hit single off her Unbroken album, "Skyscraper." Lovato sat down with MTV News before the big event and told us just how thrilled she is to be a part of the big show.
"I just know I'm performing at Jingle Ball and that I'm really excited," Lovato said. "I'm going to the Aéropostale store and I'm announcing the Jingle Ball lineup."
Of course, Gaga and Lovato aren't the only acts hitting the stage.
"I used to go to her concerts and now I'm performing with her," Lovato said of sharing the stage with Clarkson.
But wait, there's more! Gym Class Heroes, rockers Foster the People and pop newbies Hot Chelle Rae will also perform before the New York crowd.
