Christmas isn’t for another seven weeks… But Demi Lovato is already spreading holiday cheer.

The 21-year-old part-Mexican singer/actress and The X Factor judge performed her latest single “Let It Go,” from the upcoming movie Frozen, during the taping of the  Disney Parks Christmas Day Parade television special at Disneyland on Saturday afternoon in Anaheim, California.

Before leaving the amusement park, the blue-streaked starlet even posed for a photo with Minnie Mouse.

But Lovato wasn’t the only celebrity on hand for the taping…

Jordin Sparks and Jason Derulo belted out a rendition of “Baby It’s Cold Outside” while Mary J. Blige entertained the crowd with “Have Yourself a Merry Little Christmas.”
