Ellen DeGeneres Dresses as a Kardashian for Halloween PLUS! Other TV Stars' Costumes [PICS]

Halloween is officially still hours away, but Ellen DeGeneres has begun the trick or treating celebrations. On her Oct. 30 show, the comedian-host hilariously showed up as Karla Kardashian, the long-lost Kardashian sister.

Dressed in tights and an animal print V-neck blazer, DeGeneres flaunted exaggerated butt pads and fake breasts, mocking the Kardashians' signature style. She finished the look with oversized glasses and frizzy wig.

"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," DeGeneres, 57, introduced herself on her show's opening. "Since I'm the younger sister I get all the hand me downs 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. 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," she jokingly added.

DeGeneres also treated her fans to a video spoof of the latest teaser of "Keeping Up With the Kardashians." Watch her whole stunt below:

Aside from DeGeneres, here are other TV stars joining the early Halloween celebrations.

All the "Today Show" hosts came to their Halloween special as their favorite Peanuts characters, led by Al Roker, who dressed as Charlie Brown.

Kelly Ripa and Michael Strahan of "Kelly and Michael" came in as Superbowl's Katy Perry and her left shark.

"Arrow's" Colton Haynes spoofed "The Little Mermaid" and sported the Ursula look.

And Demi Lovato gamely guested at MTV's Halloween special as a trap queen.

Meanwhile, the Kardashian clan, who is known for their grand Halloween costumes, celebrated the occasion early with Kourtney and her children dressed as superheroes. Kim's daughter North, who is included in the picture, is dressed as a unicorn.

Kylie Jenner also posted a picture of her and her friends in a Halloween party. Dressed in a tight top and short skirt, Jenner seemed to be going for a sexy eskimo look.

Matriarch Kris Jenner, who is yet to unveil her look, has taken to Instagram to give approval of DeGeneres' Kardashian spoof. "The secret is out! My sixth daughter Karla!" she wrote.
