Addison Montgomery is officially out the door at Seattle Grace and coming to Oceanside. We've compiled a gallery of photos from the Private Practice series opener, set for September 26 and entitled, fittingly, "In Which We Meet Addison, A Nice Girl From Somewhere."

They don't give away much, but it appears a Grey's Anatomy star (other than Kate Walsh, that is) makes appearance in the first episode!

Find out who, and check out the official stills in our gallery.
