On Thursday's show, the Emmy award-winning host, 57, took on the identity of Kara Kardashian.
"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."
The comedian donned a plunging zebra print top that revealed giant prosthetic breasts. She also sported a pair of leggings and Shape Ups. DeGeneres posted a photo on Instagram saying: "Don't miss my Halloween show tomorrow! Love, Karla Kardashian."
"Since I'm the younger sister I get all the hand me downs," DeGeneres joked on-air. "These are Kim's Shape Ups I'm wearing, this is Khloe's old blouse, and the booty is all mine!"

The Covergirl makeup brand ambassador did away with her usual natural look, and adopted the Kardashian bronzed contour. She also covered her blonde pixie cut with an enormous black wig and oversized glasses. Degeneres also showed a spoof for an upcoming season for Keeping Up With the Kardashians.
"I'm a big part of the family, but for some reason I'm always cut out of the show. I understand because they only have 12 reality shows that are on TV 80 hours a week but they didn't have room for me."
