Looks like the fall season could be all about hot stairwell kisses! ABC has picked up the Grey's Anatomy spin-off for fall, and will be shipping Addison Shepherd (Kate Walsh) off to L.A. (and Tim Daly?) from Seattle Grace. As of now, according to Variety, the show will be called Private Practice -- kind of sexy, in a we-flirt-behind-closed-doors-but-still-are-serious-doctors sort of way.
