Khloe Kardashian Takes Over the 'Ellen' Show

— -- After hosting her short-lived talk show "Kocktails with Khloe," the youngest of the three Kardashian sisters, Khloe, was ready to move up to the big leagues.

The "Keeping Up with the Kardashians" star did her friend DeGeneres "a favor" when she took over as host of Wednesday's "Ellen DeGeneres Show."

After bringing Kardashian on stage, DeGeneres turned to her and said, "While you're here, I just have a favor...The favor is if you could just take over the show for me today."

Fortunately, Kardashian, 31, was game.

"I've done Miami, I've done the Hamptons, I can take over Burbank," she said. "Let's do this!"

As usual, Kardashian got a little assistance from one of her sisters.

She surprised older sister Kourtney Kardashian with a quick chat on FaceTime.

"Wait are you hosting the 'Ellen' show?" Kourtney inquired.

"Can you believe she left me here to do this?" Khloe responded. "I'm literally trembling with fear."

"You're so legit!" Kourtney quipped.

And since this was "Ellen," the two played a fill-in-the-blank game using their siblings.

"Who is the messiest Kardashian," Khloe asked, to which Kourtney responded Kylie Jenner.

Kourtney also voted Kim Kardashian the sister who complains the most and Khloe the biggest troublemaker.
