Grey's Anatomy, Private Practice Worlds to Collide

Reports have surfaced that a multi-episode event planned for February sweeps will bring Dr. Addison Montgomery back to Seattle Grace yet again - and possibly bring Grey's Anatomy characters to L.A. and the set of Private Practice as well.

Addison returned for one episode of Grey's Anatomy last spring, when the medical drama returned for a brief stint after the resolution of the writer's strike and Private Practice remained on hiatus. She bolted Grey's at the end of its third season.
