Showtime has officially announced that Ed Westwick (Gossip Girl), Eva Amurri (Saved!), and Embeth Davidtz (In Treatment) will guest star on David Duchovny-led Californication when the show returns for its third season this fall. The press announcement also included the news that Rick Springfield will also appear, but EW’s Michael Ausiello exclusively broke that news on Tuesday. The four will join recently announced guest stars for season three, including Kathleen Turner, Diane Farr, and Peter Gallagher. Season three finds Hank (Duchovny) taking a position as a college professor. According to the release, “he’ll attempt to shape the minds of the next generation of scribes while trying to hold down a ‘regular’ job and keep wild child daughter Becca (Madeleine Martin) on the straight and narrow.”

As for the new guest stars, Westwick plays Balt, “a student of Hank’s with a fascination for vampire lit” in episode 2. Amurri also plays a student, while Davidtz will appear as Felicia Koons — wife of the school’s dean (Gallagher) — in 10 episodes. And as we already reported, Springfield will play himself in four episodes, although right now, Showtime is officially saying he will appear in “at least one episode.”
