It seems that Lauren Conrad has caught the acting bug.

Fresh off her cameo on The CW's "Privileged," the " Laguna Beach" and " The Hills" star will guest star on ABC Family's college comedy "Greek."

On the episode "Hell Week," "Greek's" mid-season finale airing Tuesday, Oct. 28, LC will appear in a dream sequence to offer wise counsel to Casey (Spencer Grammer). When Casey learns that Max (Michael Rady) is heading to Cal Tech for grad school while she's been offered an internship, she's torn about how to spend her summer. In her dream, which also includes BFF Ashleigh (Amber Stevens), Casey seeks advice from LC, who had faced a similar decision once upon a time.

"I had so much fun on the set," enthuses Conrad, 22. "Everyone was so welcoming. I'm really excited to get to be on a show that I already love."

Meanwhile, Rusty (Jacob Zachar) is determined to face the Hell Week humiliations that the Kappa Taus will dream up for their pledges.

Conrad is in good company. It was previously announced that actor-singer Jesse McCartney and comedian Ken Marino will guest star in the second half of the season, which will premiere in Spring 2009.
