Demi Lovato Sings Mariahs All I Want For Christmas Is You

what demi wants for christmas is you

One of my favourite Christmas songs is Mariah Careys All I Want For Christmas Is You. The X Factor's Demi Lovato has recorded a cover of the Mariah Carey Christmas number.

Demi performed her rendition of Mariah's festive hit for the TNT television special Christmas In Washington on Saturday. Demi recorded her performance earlier this month.

Demi had shared her excitement over the event on Twitter, writing: "OH MY GOD.. I just met the PRESIDENT OF THE UNITED STATES!!!!! Our First Lady is GORGE. So excited right now!!!

"Such an honour singing for the President and the First Family."

Here now is Demis rendition of the song.
