Lady GaGa, Kelly Clarkson and Demi Lovato were some of the musical guests at the Z100's star-studded Jingle Ball concert. The Mother Monster gave the crowd packing inside Madison Square Garden a spectacle with her elaborate set which was filled with a mix of new and old materials. Meanwhile, Kelly and Demi surprised their fans with a live duet.
GaGa performed such songs as "The Edge Of Glory", "Judas", "Bad Romance", "Telephone" and "Poker Face". She got nostalgic with "Just Dance" while recalling her first performance at the Jingle Ball in 2008. "I'll never forget it," she gushed. "There were a whole bunch of superstars here and nobody knew who the hell I was. And this song had just started playing on the radio."
The New Yorker got into the spirit of holiday by bringing to the stage a Christmas-tree shaped keytar. She also treated the audience with her own rendition of Bing Crosby's festive classic "White Christmas". "This song's too short," she cracked an R-rated joke when explaining the extra verses she added to the song. "Just when I get into it, it stops. It's like a really bad orgasm."
While GaGa grabbed attention with her twisted version of "White Christmas", Kelly and Demi drew cheers from their devotees by giving a tease of how they would sound like if they recorded a duet together. The "American Idol" graduate and the former Disney star belted out "Have Yourself a Merry Little Christmas".
Soon after sharing the stage with Kelly, Demi reached out to her Twitter followers to express her excitement. "I. Just sang. With Kelly. Clarkson. #ahhhhhhh," the former star of "Sonny with a Chance" wrote. Almost at the same time, the "Idol" singer posted on her account, "girl we have got to sing together again! You have such a powerful and beautiful voice! I love your spirit."
Celebrity guests included Khloe Kardashian, while the other stars performing at the annual music event on Friday night, December 9 were Foster the People, Karmin, Pitbull, Neon Hitch, The Script, LMFAO, David Guetta and Gym Class Heroes. All of them knew how to keep the crowd on their toes by performing their hit singles.
At the backstage, some of those stars revealed their duet dream when doing an interview with the press. To MTV, RedFoo said, "Probably GaGa," before adding, "Let's do some dancing, let's do some partying, see what we can do, you know? Some fashion, come out there - it could be amazing."
Guetta also mentioned the Monster ringleader when asked about whom he wants to work with. "Listen, I'm ready, you should ask her! That would be great, of course," he gushed. "She's really a creative genius, and I told her the other day that I saw her last video ['Marry the Night'] and, again, amazing. I love creative people; it's what I live for. Obviously, she's really amazing."
