Demi Lovato Covers “All I Want For Christmas Is You” At ‘Christmas In Washington’ Concert

Demi Lovato‘s performance of “All I Want For Christmas is You” at this year’s Christmas in Washington is sure to surprise the people who were unaware The X Factor judge could belt like that — but the Disney-bred star never faltered as she hit some crazy-high (we’re talking Mariah Carey-high!) notes while performing in front of Barack Obama and his family.

The holiday special was hosted by Conan O’Brien for the second year in a row and featured a grab bag of other artists including Scotty McCreery, Diana Ross and PSY. Listen to Demi’s cover up top, then head after the jump to see her perform “Silent Night,” too.
