Kathy Griffin is looking forward to causing trouble when she guest stars on the Lifetime series "Drop Dead Diva."
In an episode of the upcoming third season, Griffin plays the sister of series regular Kate Levering's Kim and clashes with Margaret Cho's character, Teri.
Griffin said acting as a total witch to her good friend Cho is "the role I was born to play."
Other "Drop Dead Diva" guest stars for the coming season include Wanda Sykes, LeAnn Rimes and Paula Abdul.
"Drop Dead Diva" stars Brooke Elliott as a shallow model who dies in an accident and finds her soul has entered the body of a brilliant, plus-size attorney.
