ABC Planning Grey’s Anatomy, Private Practice Crossover Episodes

TV Guide is reporting that ABC is planning a multi-episode crossover story with Grey’s Anatomy and its spin-off, Private Practice. They are looking to air the crossover episodes during February sweeps. Still in the development stage, the number of episodes and the actors involved has yet to be decided. Kate Walsh’s Dr. Addison Montgomery will again return to Seattle Grace, as she did for one episode last spring. Grey’s Anatomy is currently in its fifth season on ABC. The concept for Private Practice first emerged in the form of a back-door pilot/May 2007 episode of Grey’s Anatomy in which Addison ventured to Los Angeles to catch up with her friend Naomi.
