Ellen Degeneres Is Kim Kardashian's Sister? See Host's Hilarious 'Karla Kardashian' Halloween Costume

Ellen Degeneres never fails with her Halloween costumes. This time, she is channeling a Kim Kardashian-like booty!

Oh, and also she goes by the name of "Karla Kardashian," the "Keeping Up Wit The Kardashians" star's long-lost sister.

Ellen Degeneres has had tons of Halloween costumes and impersonations before - as Nicki Minaj, Sofia Vergara and others.

This year, for her show's Halloween-themed episode, the TV host dressed as "Karla Kardashian," Kim Kardashian's never-heard-of sister.

"I'm the lesser known Kardashian sister, my name is Karla Kardashian with a K," Degeneres said. "We're known for our double K's these are double Ks too by the way,"

For Ellen Degeneres Halloween costume this year, the TV host sported gigantic prosthetic breasts worthy of Kim Kardashian's, a plunging zebra print top, leggings and running shoes. She was also waering a crazy black wig and glasses, which made her look like a nerdy, mismatched Cher.

"Since I'm the younger sister I get all the hand me downs," the TV host explained. "So these are Kim's Shape Ups I'm wearing, this is Khloe's old blouse, and the booty is all mine!"

"I'm a big part of the family, but for some reason I'm always cut out of the show," "Karla Kardashian" said. "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."

The 57-year-old TV show host also spoofed the trailer for the new season of "Keeping Up With The Kardashians."

All throughout the episode, Ellen Degeneres donned the Karla Kardashian costume, even during her celebrity guests, Josh Duhamel and Ariana Grande.

Before the episode, Degeneres posted a teaser photo of the newly-introduced Kardashian sister on Instagram.

"Don't miss my Halloween shot tomorrow! Love, Karla Kardashian," Degeneres wrote.
