A familiar face will be popping up at Seattle Grace before Grey's Anatomy goes on hiatus at the end of the season. Kate Walsh, a.k.a. Addison Montgomery, M.D., will return to the medical drama when her character makes a visit to the Emerald City. It'll be for just one episode, though. ABC has already picked up Kate's spin-off series, Private Practice, for the fall.

Executive producer/writer Shonda Rhimes confirmed that Kate Walsh will return to Grey's Anatomy for a guest bit this spring, but a definite date has not been pinned down. Five new episodes of GA are set to air starting April 24.

As most of you know -- since fans of Grey's are likely to be interested in this item in the first place -- Practice follows Addison's life, professional and personal, since leaving the high tech hospital in Seattle for an office and clinic in L.A.

While ABC has shown faith in the show by giving it an early renewal, the reception for Practice has been so-so. Certainly not the wow that Grey's was when it began, but clearly the network is willing to give Rhimes and company a chance to find their groove. And a bigger audience, too.
