In a special Halloween episode that airs Friday, the talk-show host is dressing up as "Snooki's Pouf," a tribute to Jersey Shore's pint-sized princess's signature do.
DeGeneres, 52, dons a full-body costume covered in hair. A Cabbage Patch-style doll – which is a shade or two tanner than your average children's toy – dangles between her legs.
"That's Snooki down there," she says of the doll. "I'm the pouf. She's the actual size. She is that short. I met her in person. I was almost late for the show because I didn't take in account how long it takes to gym, tan and laundry, everybody."
Also joining in on the Halloween festivities: Vanessa Williams, who dresses up as a baby girl and Dancing with the Stars's power partners, Brandy and Maksim Chmerkovskiy, who are paying homage to Disney as Minnie Mouse and Prince Charming, respectively.
