Rob Lowe

Rob Lowe will guest-star in Season 4 of Californication, Showtime announced Monday.

Lowe — best known for his roles on The West Wing and Brothers & Sisters — will play Eddie Nero, a self-obsessed, award-winning movie star who is in contention to play the film version of Hank (David Duchovny). Lowe is slated to appear in one episode, but could possibly recur.
