Ellen DeGeneres debuted her Halloween costume on her show Friday, revealing that this year she’s dressing up as Karla Kardashian – the other sister.

Ellen DeGeneres As Karla Kardashian

“Hi everybody, I bet you’re wondering who I am. Obviously if you are wondering who I am, you probably haven’t seen the trailer for the latest season of the Kardashians,” DeGeneres said before playing the trailer with her – or rather Karla’s – likeness added into the footage.

After the trailer concluded, DeGeneres deadpanned, “That’s right. I’m the lesser known Kardashian sister, my name is Karla Kardashian with a K, we’re known for our double K’s. These are double Ks too by the way,” she added, gesturing at her chest.

“Since I’m the younger sister I get all the hand-me-downs,” DeGeneres went on. “So these are Kim’s Shape Ups I’m wearing, this is Khloe’s old blouse, and the booty is all mine!”

DeGeneres has been teasing her costume this week ahead of the Halloween special that airs later today. “Don’t miss my Halloween show tomorrow! Love, Karla Kardashian,” DeGeneres captioned an Instagram snap of herself in the plunging leopard top, stirrup leggings and sneakers.
