Nip/Tuck will be hosting an astounding list of guest stars in the fourth season including Kathleen Turner, Richard Chamberlain, Rosie O'Donnell, Brooke Shields, Catherine Deneuve, Melissa Gilbert, and Alanis Morissette. Rosie O'Donnell is slated to appear as Dawn Budge, a woman who has plastic surgery after she wins the lottery, and has a fling with her surgeon. O'Donnell was apparently shy about doing her sex scene with Julian McMahon (Dr Christian Troy.) Some rumors claim this plotline may be a lead-in to a spinoff starring O'Donnell. Alanis Morisette will be playing a new love interest for lesbian anesthesiologist Liz (Roma Maffia.) Morisette will appear in three episodes beginning October 31. Season four of Nip/Tuck airs Tuesdays on the FX network.
