Spilling the family secrets! Khloé Kardashian took over hosting duties for Ellen DeGeneres during her latest show (due to air today, Wednesday, June 8). And the cunning Kardashian used her family connections to bring some more star power to the episode.

The reality TV star thought she was going to be a guest on The Ellen DeGeneres Show when she came to the studio as a surprise visitor.

But as it turned out, DeGeneres had a another plan. "While you're here, I have a favor," she asked the surprised 31-year-old. "The favor is if you would just take over the show for me today?" the 58-year-old TV star asked.

"OK," replied Kardashian. "I've done Miami, I've done the Hamptons, I can take over Burbank.”

DeGeneres then reintroduced her audience to her hilarious alter ego, Karla Kardashian, and asked Khloé to do as good a job as the spare Kardashian sister had done on Halloween.

Feeling the pressure, Khloé decided her best option was to enlist the help of one of her favorite siblings, so she jumped on the phone to Kourtney Kardashian and invited her to join her in the studio via FaceTime.

"I'm literally trembling with fear," Khloé admitted as she asked her sister to play a game with her, which entailed spilling a few family secrets.

"Who is the messiest Kardashian?" asked Khloé.

"Kylie," replied the mom-of-three, without hesitation.

"The biggest troublemaker?"

"Khloé," responded Kourtney.

"The sister who complains the most?"

"Kim?" asked Kourtney, not entirely convinced of her own answer.

"Duh! It's so Kim," replied Khloé.

Watch the funny video above and see what happened when cheeky Kourtney challenged Khloé to dance (and twerk!) for her audience.
