Check out Demi's best career moments.
Demi Lovato channeled her inner rocker as she stepped on stage in New York City last night. Showing off her new fiery locks, Demi belted out hit after hit at this year’s Jingle Ball 2011 hosted at Madison Square Gardens.

Despite performing for a star-studded crowd that included Khloe Kardashian and Lady Gaga, Demi had no trouble getting through her set. She even invited a fellow songstress on stage for a special duet!

American Idol winner Kelly Clarkson joined Demi on stage for a performance of “Have Yourself a Merry Little Christmas.” Demi, who has always looked to Kelly as one of her musical inspirations, later on tweeted about her excitement:

Oh my God….. Oh my God…. Oh my God…..#shaking

Meanwhile, Kelly also shared her enthusiasm to share the stage with the former Disney starlet. She tweeted to Demi:

girl we have got to sing together again! You have such a powerful and beautiful voice! I love your spirit…

Do we smell a future collaboration? We certainly hope so!
