Isn’t it ironic that Alanis Morissette has a song called “Not the Doctor,” yet she’ll be the love interest of one while she guest-stars on Nip/Tuck? Morissette, who gets caught up in a tryst with anesthesiologist Dr. Liz Cruz (Roma Maffia ), began taping the first of three episodes last week. (Look for her on the Oct. 31 episode.)

What do you think, PopWatchers? Brilliant idea? Or has Nip/Tuck just filled the stunt-casting void left by the retirement of Will & Grace?
