The last time we were this blown away by someone other than Mariah Carey singing this, it was that 10-year-old girl in Love, Actually who grew up to Marceline the Vampire Queen on Adventure Time!
So consider yourself in good effing company, Demi Lovato!
The X Factor judge just wrapped her first - and possibly final - season on the reality competition just this week, and now that she's done coaching up-and-comers on a full-time basis, she reminded us all why she was awarded the position in the first place with an absolutely STUNNING rendition of the MiMi holiday staple All I Want For Christmas Is You!
And all in honor of President Barack Obama and his FAMILY!
Ch-ch-check out the former Disney princess during Saturday night's Christmas in Washington Concert (above)!
We just ADORE that she was able to make such a well-known song all her own…and still sound flawless in the process!
There's really no comparing her voice to Mariah's, but in this case, that's okay!
Gah! We are just feeling TOO festive now!
Thanks for bringing the Christmas spirit HARD this year, gurl!
We're sure POTUS and company couldn't have been more thrilled!
