Rosie O'Donnell and Celine Dion tackle the lovely "The Magic of Christmas Day" on one of the Commack native's variety specials. (Um, isn't it about time for another one of those? Please?) Though Rosie has been out of the headlines recently, happily doing her "Rosie Radio" show on Sirius, and spending more time at home with her kids, she will be on the next season of "Who Do You Think You Are?" on NBC in February, where they will trace her ancestry.
