Of course Reese Witherspoon loves Christmas. Can’t you imagine her starring in a holiday romantic-comedy called Antarctica’s Sweetheart, in which she plays the princess of the elf kingdom who has to find an elf husband before she turns elf 40 or else she can’t become queen of the elves? (Spoiler Alert: She doesn’t do it in time but becomes queen anyway. How? You’ll have to pay $15 to find out. Santa’s involved.) Here she is singing Christmas carols with altered lyrics on The Tonight Show.
