Demi Lovato isn’t afraid to tackle Mariah Carey’s music this holiday season…

During TNT‘s Christmas in Washington special, which aired Friday night, the 20-year-old part-Mexican singer/actress and The X Factor judge performed Carey’s classic “All I Want for Christmas” with President Obama and the First Family in the front row.

Late-night talk show host Conan O’Brien served as host of the telecast, which was taped in Washington D.C.’s National Building Museum.

Additional performers included former American Idol winner Scotty McCreery, who recently released an album of holiday music, as well as Smash star Megan Hilty and former The Voice finalist Chris Mann.
