Katie Couric is joining the Jon and Kate Plus 8 media circus—by dressing up as one of the couple's sextuplets for Halloween. Though Couric could easily pull off a Kate costume, she's opted instead to be Aaden, the oldest of the fraternal bunch. "You have to make sure to wear the glasses at the end of your nose," Couric told Extra. Imitation can be a form of flattery, and Couric made sure to mention her costume to Kate Gosselin when they met in person. Of the now divorced mom of eight, Couric said, "she seems very nice."
