Larry Hagman and Kathleen Turner have signed on to appear in several episodes of Nip/Tuck on FX.

Also joining the cast is Brooke Shields who will guest star on the hit drama, says The Hollywood Reporter. One of the story lines on the show's upcoming fourth season will revolve around a beautiful thirtysomething woman (Sanaa Lathan) and her wealthy, much older husband (Hagman) who wind up buying McNamara/Troy plastic surgery, the Miami-based plastic surgery practice of Dr. Sean McNamara (Dylan Walsh) and Dr. Christian Troy (Julian McMahon).

The fourth season of Nip/Tuck will begin in the fall on FX.
