Also showing off her talents in the Lake Buena Vista locale was "American Idol" alum Jennifer Hudson, as the 30-year-old was backed up by a full choral group during a medley of holiday hits.
On the other coast of the States, Christina Aguilera joined alongside Minnie Mouse as she belted out “Have Yourself A Merry Little Christmas“ to the delight of the Disney Grand Californian Hotel & Spa crowd lining the stage in Anaheim, CA.
