She and Minnillo play "two women who've managed to concoct a very interesting scheme that ends in murder," executive producer Pam Veasey told People.com of the episode, which will air Dec. 16.

Kardashian is pumped for the part.

"I am so excited to be working with Vanessa again. I am fascinated by crime scene investigating," she said. "I swear, I wish I was a crime scene investigator sometimes!"

Added Kardashian, "I'm having such a good time expanding my roles. I truly love branching out into different characters."
