There could be a multiple episode crossover between 'Grey's Anatomy' and its spin-off 'Private Practice' in February 2009.
"Grey's Anatomy" and its spin-off "Private Practice" may cross each other's path, TV Guide reports exclusively. Some sources told the publication that there will be a multi-episode crossover story that comes in February next year.
No confirmation yet on which characters will visit the other show, but TV Guide specifies that Kate Walsh's Addison Montgomery will return to her former work place, the Seattle Grace Hospital. In an interview with the publication also, Walsh shares out her thought of who from "Grey's" should make a visit to "Private". On this she pointed on Eric Dane's Mark Sloan, saying "It'd be fun to have him cause some trouble!"
No confirmation yet for both the cross-over and who will be making the guest-appearances.
Addison once made a return for a specialized surgery to "Grey's" several months after "Private" aired in 2007.
