No Ellen wasn’t dressed as one of the reality TV stars from the show, instead she was Snooki’s Pouf and yes we are referring to the top piece of hair on Nicole’s head.
On the show Ellen said:
“In case you don’t know, I’m Snooki’s Pouf,” adding “That’s Snooki down there,” she added while pointing at the Cabbage Patch doll at her feet. “I’m the pouf. She’s the actual size. She is that short. I met her in person.”
It’s definitely a weird costume, but props to Ellen for coming up with something original.
