MARGE FINDS A SPECIAL CHRISTMAS HELPER AND THE FAMILY PREPARES FOR A TROPICAL HOLIDAY ON AN ALL-NEW "THE SIMPSONS" SUNDAY, DECEMBER 5, ON FOX

Lifestyle Guru Martha Stewart Makes Guest Voice Appearance

Pop Star Katy Perry Guest-Stars in Special Live-Action Sequence Featuring THE SIMPSONS Puppets

It's beginning to look a lot like Christmas in Springfield, but while Marge gets in the holiday spirit, it's bah humbug for the rest of the family. Disappointed that she is alone spreading the holiday cheer, Marge sends a letter to Martha Clause (guest voice Stewart) to help her save the family Christmas. Martha comes to the rescue and transforms the house into the North Pole chalet Marge has always dreamed of, but when the family is noticeably absent from the perfectly trimmed holiday home, she realizes that it's Homer and the kids who make the holidays special. Meanwhile, the Simpsons get ready to sneak away for a tropical holiday vacation in Hawaii, but surprise visitors Mr. Burns and Moe's new friend, Katy Perry (guest-starring as herself in a special live-action sequence) delay their getaway. Four special holiday tales will be spun in the all-new "The Fight Before Christmas" episode of THE SIMPSONS airing Sunday, Dec. 5 (8:00-8:30 PM ET/PT) on FOX. (SI-2122) (TV-PG L, V)
