The dimmest bulb on the tree shows off her holiday spirit on this jazzy pop outing -- but before you laugh at her spelling, know that the disc was titled after her late granny.

CHESTNUTS ROASTED: Let it Snow; Baby it's Cold Outside (with saintly hub Nick); Little Drummer Boy (with lip-synching sis Ashlee).

YULE LOVE: Guessing where Jess thinks chestnuts come from.

YULE WISH: Her 15 minutes were up already.
