The doctor is in!
According to TV Guide, June Diane Raphael is joining the cast of New Girl as Dr. Sadie, Jess's (Zooey Deschanel) lesbian gyno friend who diagnoses an ailing Schmidt (Max Greenfield). (Contrary to what we previously reported, Nick isn't the one in need of medical attention.) She'll make her first sure-to-be-hilarious appearance in Episode 9.
